Pre-Contact era Austronesian migrations into the islands of the
Indo-Pacific|368x368px Guam and the other
Mariana Islands were the first islands settled by humans in
Remote Oceania. It was the first and the longest of the ocean-crossing voyages of the
Austronesian peoples, and is separate from the later
Polynesian settlement of the rest of Remote Oceania. They were first settled around 1500 to 1400 BC, by migrants departing from the
Philippines. This was followed by a second migration from the
Caroline Islands in the first millennium AD. A third migration wave took place from
Island Southeast Asia, likely the Philippines or eastern
Indonesia, by 900 AD. These original settlers of Guam and the
Northern Mariana Islands evolved into the
Chamorro people, historically known as Chamorros after first contact with the Spaniards. The ancient Chamorro society had four classes: (chiefs), (upper class), (middle class), and (lower class). The island became a rest stop for
whalers starting in 1823. After
a smallpox epidemic killed 3,644 Guamanians in 1856, Carolinians and Japanese were permitted to settle in the Marianas. The US Navy assumed administrative control, with Captain Richard P. Leary appointed as the first naval governor in 1899. This era marked the introduction of American governance structures and cultural influences to the island. The naval administration prioritized the development of Guam's infrastructure to support its strategic military position in the
Pacific. One notable project was the establishment of a coaling station to service naval vessels traveling between Hawaii and the
Philippines. Additionally, efforts were made to improve the island's roads, sanitation systems, and public health facilities. Educational reforms were also introduced, including the establishment of public schools with English as the medium of instruction, aiming to assimilate the local
Chamorro population into American culture. Despite these developments, the Chamorro people faced significant challenges under the naval administration. Civil liberties were limited, and the local population had minimal input in governmental decisions. Recognizing these constraints, Chamorro leaders petitioned for U.S. citizenship and greater political autonomy as early as 1901, though these efforts were largely unsuccessful during this period.
World War I On December 10, 1914, the
SMS Cormoran, a German armed
merchant raider, was forced to seek port at
Apra Harbor after running short on coal after pursued by the Japanese. The United States, which was neutral at the time refused to supply provisions sufficient for the
Cormoran to reach a German port, so the ship and her crew were interned until 1917. On the morning of April 7, 1917, word reached Guam by telegraph cable that the
U.S. Congress had declared war on Germany. The Naval
Governor of Guam,
Roy Campbell Smith, sent two officers to inform the
Cormoran that a state of war existed between the two countries, that the crew were now
prisoners of war, and that the ship must be surrendered. Meanwhile, the
USS Supply blocked the entrance to Apra Harbor to prevent any attempt to flee. In a separate boat, the two officers were accompanied by a barge commanded by Lt. W.A. Hall, who was designated prize master, and had brought 18 sailors and 15 Marines from the barracks at
Sumay. Seeing a launch from
Cormoran hauling a barge of supplies back shore, Hall ordered shots fired across the bow of the launch until it hove to. Meanwhile, the two officers reached
Cormoran and informed Captain
Adalbert Zuckschwerdt of the situation. Zuckschwerdt agreed to surrender his crew but refused to turn over the ship. The U.S. officers informed Zuckschwerdt that the
Cormoran would be treated as an enemy combatant and left to inform Governor Smith of the situation. Unbeknownst to the Americans, the Germans had secreted an explosive device in the ship's coal bunker. Minutes after the Americans left, an explosion aboard
Cormoran hurled debris across the harbor and her crew began abandoning ship. The two American boats and USS
Supply immediately began to recover German sailors from the water, saving all but seven of the roughly 370
Cormoran crew. This incident, including the warning shots against the launch, accounted for the first violent action of the
United States in World War I, the first shots fired by the U.S. against Germany in World War I, the first German prisoners of war captured by the U.S., and the first Germans killed in action by the U.S. in World War I. During the nearly three years of occupation approximately 1,100 Chamorros were killed, according to later US
Congressional committee testimony in 2004. Some historians estimate that war violence killed 10% of Guam's 20,000 population. The Governor of Guam was federally appointed until 1968 when the
Guam Elective Governor Act provided for the office's popular election. Since Guam is not a U.S. state, U.S. citizens residing on Guam are not allowed to vote for president and their only representation in the U.S. Congress is a non-voting member in the House of Representatives. spent 28 years in a self-dug
cave in the jungle of Guam, where he hid to avoid capture by US forces in World War II. In 1969,
a referendum on unification with the Northern Mariana Islands was held and rejected. In the 1970s,
Maryly Van Leer Peck started an engineering program, expanded
University of Guam, and founded
Guam Community College. In the late 1970s,
Alby Mangels, Australian adventurer and filmmaker of
World Safari visited Guam during his six-year escapade on the Pacific leg of his voyage aboard the
Klaraborg. In 1963, the removal of Guam's security clearance by President John F. Kennedy allowed for the development of a tourism industry. In the early 1990s, when the United States closed
U.S. Naval Base Subic Bay and
Clark Air Base bases in the
Philippines after the expiration of their leases, many of the forces stationed there were relocated to Guam. The
1997 Asian financial crisis, which hit Japan particularly hard, severely affected Guam's tourism industry. Military cutbacks in the 1990s also disrupted the island's economy. Economic recovery was further hampered by devastation from super typhoons
Paka in 1997 and
Pongsona in 2002, as well as the effects of the
September 11 terrorist attacks and the crash of
Korean Air Flight 801 on tourism. == Geography and environment ==
