Territory of Alaska - Middle 20th Century

Middle 20th Century

Then, in 1920, the Jones Act required U.S.-flagged vessels to be built in the United States, owned by U.S. citizens, and documented under the laws of the United States. All goods entering or leaving Alaska had to be transported by American carriers and shipped to Seattle prior to further shipment, making Alaska dependent on the state of Washington. The U.S. Supreme Court ruled that the provision of the Constitution saying one state should not hold sway over another's commerce did not apply because Alaska was only a territory. The prices Seattle's shipping businesses charged began to rise to take advantage of the situation.

The Great Depression caused prices of fish and copper, which were vital to Alaska's economy at the time, to decline. Wages were dropped and the workforce decreased by more than half. In 1935, President Franklin Delano Roosevelt thought Americans from agricultural areas could be transferred to Alaska's Matanuska-Susitna Valley for a fresh chance at agricultural self-sustainment. Colonists were largely from northern states, such as Michigan, Wisconsin, and Minnesota under the belief that only those who grew up with climates similar to that of Alaska's could handle settler life there. The United Congo Improvement Association asked the president to settle 400 African-American farmers in Alaska, saying that the territory would offer full political rights, but racial prejudice and the belief that only those from northern states would make suitable colonists caused the proposal to fail.

The exploration and settlement of Alaska would not have been possible without the development of the aircraft, which allowed for the influx of settlers into the state's interior, and rapid transportation of people and supplies throughout. However, due to the unfavorable weather conditions of the state, and high ratio of pilots-to-population, over 1700 aircraft wreck sites are scattered throughout its domain. Numerous wrecks also trace their origins to the military build-up of the state during both World War II and the Cold War.

Alaskan participation in World War II was one of great importance. From June 1942 until August 1943 the Japanese tried to invade the U.S. by way of the Aleutian island chain, in the Battle of the Aleutian Islands. This marked the second time since the War of 1812 that American soil was occupied by a foreign enemy, the first being the occupation of the island of Guam in December 1941, also by the Japanese. The Japanese were eventually repelled from the Aleutian Islands by a force of 34,000 troops.
