Archeological and paleontological theory suggests that Homo sapiens existed in Palawan about 50,000 BC. The Negritos are thought to have arrived in the area that is now the Philippines more than 30,000 years ago, perhaps via land bridges that connected the area to the Asian continent during an ice age.

The ancestors of the vast majority of the Filipino people, the Austronesians from Taiwan, settled in northern Luzon around 2500 BC. They spread to the rest of the Philippines and later colonized most of Maritime Southeast Asia and the Western Pacific Islands. Arab, Chinese and Indian traders made contact with the Philippines during the course of the next thousand years until the arrival of the Europeans.

Sailing for the Spanish, the Portuguese explorer Ferdinand Magellan and his crew were the first Europeans to arrive in the archipelago in 1521. Magellan was killed by indigenous warriors in Mactan Island while being involved with political conflicts with Lapu-Lapu. The beginnings of colonization came when the King Philip II of Spain (for whom the Philippines is named) ordered a follow-up expedition. The conquistador, Miguel López de Legazpi arrived from Mexico in 1565 and formed the first Spanish settlements in Cebu. In 1571 he established Manila as the capital of the new Spanish colony.

Roman Catholic missionaries converted most of the inhabitants. In the next 333 years, the Spanish military fought off various local indigenous revolts and various external colonial challenges. Such challenges came from the British, Chinese, Dutch, French, Japanese, and Portuguese. The most significant loss for Spain was the temporary occupation of the capital, Manila, by the British during the Seven Years' War. The Philippines was ruled as a territory of New Spain from 1565 to 1821, before it was administered directly from Spain. The Manila Galleon which linked Manila to Acapulco, Mexico traveled once or twice a year, beginning in the late 16th century. The Philippines opened itself to world trade on September 6, 1834.

A propaganda movement, which included Philippine nationalist José Rizal, then a student studying in Spain, soon developed on the Spanish mainland. This was done in order to inform the government of the injustices of the administration in the Philippines as well as the abuses of the friars. In the 1880s and the 1890s, the propagandists clamored for political and social reforms, which included demands for greater representation in Spain. Unable to gain the reforms, Rizal returned to the country, and pushed for the reforms locally. Rizal was subsequently arrested, tried, and executed for treason on December 30, 1896. Earlier that year, the Katipunan, led by Andrés Bonifacio, already started a revolution, which was eventually continued by Emilio Aguinaldo, who established a revolutionary government, although the Spanish governor general Fernando Primo de Rivera proclaimed the revolution over in May 17, 1897.

The Spanish-American War began in Cuba in 1898 and soon reached the Philippines when Commodore George Dewey defeated the Spanish squadron at Manila Bay. Aguinaldo declared the independence of the Philippines on June 12, 1898, and was proclaimed head of state. As a result of its defeat in the War, Spain ceded the Philippines, together with Cuba (made an independent country, the US in charge of foreign affairs), Guam and Puerto Rico to the United States. By 1899, the Philippine-American War ensued between the United States and the Philippine revolutionaries, which continued the violence of the previous years. The US proclaimed the war ended when Aguinaldo was captured by American troops on March 23, 1901, but the struggle continued until 1913. The country's status as a colony changed when it became the Commonwealth of the Philippines in 1935, which provided for more self-governance. Plans for increasing independence over the next decade were interrupted during World War II when Japan invaded and occupied the islands. After the Japanese were defeated in 1945, the Philippines achieved independence from the United States on July 4, 1946.

Since 1946, the newly independent Philippine state has faced political instability with various rebel groups. The late 1960s and early 1970s saw economic development that was second in Asia, next to Japan. Ferdinand Marcos was, then, the elected president. Barred from seeking a third term, Marcos declared martial law on September 21, 1972 and ruled the country by decree. Marcos extended both his power and tenure by force. His authoritarian rule became marred with unmitigated, pervasive corruption, cronyism and despotism.

Upon returning from exile, opposition leader Benigno Aquino, Jr. was assassinated on August 21, 1983. In January 1986, Marcos allowed for a "snap" election, after large protests. The election was believed to be fraudulent, and resulted in a standoff between military mutineers and the military loyalists. Protesters supported the mutineers, and were accompanied by resignations of prominent cabinet officials. Corazon Aquino, the wife of Benigno Aquino, Jr., was the recognized winner of the snap election. She took over government, and called for a constitutional convention to draft a new constitution, after the 1986 EDSA Revolution. Marcos, his family and some of his allies fled to Hawaii.

The return of democracy and government reforms after the events of 1986 was hampered by massive national debt, government corruption, coup attempts, a communist insurgency, and a Muslim separatist movement. The economy improved during the administration of Fidel V. Ramos, who was elected in 1992. However, the economic improvements were negated at the onset of the East Asian financial crisis in 1997. The 2001 EDSA Revolution led to the downfall of the following president, Joseph Estrada. The current administration of president Gloria Macapagal-Arroyo has been hounded by allegations of corruption and election rigging. Due to these allegations the current administration has had to suppress several attempted coups, the most recent taking place in Manila during March of 2006.

The Philippines constitutes an archipelago of 7,107 islands with a total land area of approximately 300,000 square kilometres (116,000 sq. mi). It lies between 116° 40' and 126° 34' E. longitude, and 4° 40' and 21° 10' N. latitude, and borders the Philippine Sea on the east, on the South China Sea the west, and the Celebes Sea on the south. The island of Borneo lies a few hundred kilometers southwest and Taiwan directly north. The Moluccas and Sulawesi are to the south, and Palau is to the east beyond the Philippine Sea.

The islands are commonly divided into three island groups: Luzon (Regions I to V, NCR and CAR), Visayas (VI to VIII), and Mindanao (IX to XIII and ARMM). The busy port of Manila, on Luzon, is the national capital and second largest city after its suburb Quezon City.

The local climate is hot, humid, and tropical. The average yearly temperature is around 26.5°C (79.7°F). There are three recognized seasons: Tag-init or Tag-araw (the hot season or summer from March to May), Tag-ulan (the rainy season from June to November), and Taglamig (the cold season from December to February). The southwest monsoon (May-October) is known as the "habagat" and the dry winds of the northeast monsoon (November-April) as the "amihan". The country itself is undergoing desertification in place like Sorsogon, Baguio, Davao and the Sierra Madre mountain range.

Most of the mountainous islands used to be covered in tropical rainforest and are volcanic in origin. The highest point is Mount Apo on Mindanao at 2,954 metres (9,692 ft). There are many active volcanos such as Mayon Volcano, Mount Pinatubo, and Taal Volcano. The country also lies within the typhoon belt of the Western Pacific and about 19 typhoons strike per year.

Lying on the northwestern fringes of the Pacific Ring of Fire, the Philippines experiences frequent seismic and volcanic activities. Some 20 earthquakes are registered daily in the Philippines, though most are too weak to be felt. The last great earthquake was the 1990 Luzon earthquake.

The longest river is the Cagayan River of northern Luzon. The nearly circular Manila Bay, is connected to the Laguna de Bay by means of the Pasig River. Subic Bay, the Davao Gulf and the Moro Gulf are some of the important bays. Transversing the San Juanico Strait is the San Juanico Bridge, that connects the islands of Samar and Leyte.

The people of the Philippines are called Filipinos. Most Filipinos are descended from the various Austronesian-speaking migrants who arrived in successive waves over a thousand years ago from Taiwan, genetically most closely related to the Ami tribe.[30] Filipinos to this day are divided into various ethnic groups, including but not limited to the Visayan, the Tagalogs, the Ilocanos, the Moro, the Kapampangans, the Bicolanos, the Pangasinense, the Igorot, the Lumad, the Mangyan, the Ibanag, the Chabacano, the Badjao, the Ivatan, and the Palawan tribes. The Negritos, including the Aetas and the Ati, are considered as the aboriginal inhabitants of the Philippines though they are estimated to be fewer than 30,000 people (0.03%).

Filipinos of Chinese descent, who had been settling in the Philippines since pre-colonization, currently forms the largest non-Austronesian ethnic group, claiming about 2% of the population. Other significant minorities, ranked according to population, include Spanish, Americans, other Europeans, Japanese, Koreans, and South Asians. There are also numerous Arabs and Indonesians residing in the country, especially in Mindanao. The Philippines has Asia's largest Eurasian, Amerasian, and American population.

Throughout the country's history, various ethnic groups as well as immigrants and colonizers have intermarried, producing Filipino mestizos. These mestizos, apart from being of mixed indigenous Austronesian and European ancestry, can be descended from any ethnic foreign forebearers. They have mixed ancestry (mostly of Spanish or Mexican, American and other European descents), and about 10% have some Chinese ancestry. An unknown number of Filipinos also have some Amerindian ancestry.

More than 170 languages and dialects are spoken in the country, almost all of them belonging to the Borneo-Philippines group of Malayo-Polynesian language branch of the Austronesian language family.

According to the 1987 Constitution, Filipino and English are both the official languages. Many Filipinos understand, write and speak English, Filipino and their respective regional languages.

Filipino is the de facto standardized version of Tagalog and the nation's official language. English is widely used as a lingua franca throughout the country, and is the second official language of the country.

Twelve major regional languages are the auxiliary official languages of their respective regions, each with over one million speakers: Tagalog, Cebuano, Ilocano, Hiligaynon, Waray-Waray, Kapampangan, Bikol, Pangasinan. Kinaray-a, Maranao, Maguindanao and Tausug.

Spanish in the Philippines was the original official language of the country for more than three centuries, but was used mainly by the educated illustrados (including José Rizal) or self taught natives and the Spanish authorities. Spanish was the language of Philippine Revolution, and the 1899 Malolos Constitution proclaimed it as the official language. Following the American occupation of the Philippines, its use declined, especially after 1940. Currently, only a few Mestizos of Spanish and Mexican descents speak it as their first language, although a few others use it together with Tagalog and English.

Both Spanish and Arabic are used as auxiliary languages in the Philippines. The use of Arabic is increasingly prevalent among Filipino Muslims and taught in madrasah (Muslim) schools.

The Philippines is one of only two majority Roman Catholic countries in Asia (the other being East Timor). About 90% of Filipinos are Christians, where 81% belong to the Roman Catholic Church, and the 9% composed of Protestant denominations, the Philippine Independent Church, and Iglesia ni Cristo. While Christianity is a major force in the culture of the Filipinos, indigenous traditions and rituals still influence religious practice.

Approximately 5% of Filipinos are Muslims, and are locally known as "Moros", having been dubbed this by the Spanish due to their sharing Islam with the Moors of North Africa. They primarily settle in parts of Mindanao, Palawan and the Sulu archipelago, but are now found in most urban areas of the country. Most lowland Muslim Filipinos practice normative Islam, although the practices of some Mindanao's hill tribe Muslims reflect a fusion with animism. There are also small populations of Buddhists, Jews and animists, which, along with other non-Christians and non-Muslims, collectively comprise 5% of the population.
