Historically, it is generally believed that Alaskans came from Asia and Bering Isthmus and developed into Indians of different tribes. The earliest recorded Europeans came from Russia and went to Alaska to catch sea otters for fur. 1867 On April 9, US Secretary of State William Civade proposed to buy Alaska from Russia for 7.2 million US dollars (equivalent to 90 million US dollars in 2003). At that time, many Americans thought it was worthless and laughed at it as "Civade's stupid behavior" or "Civade's ice box". In fact, because the middleman (a Russian) took bribes, the Russian czar government did not receive $7.2 million, and the Americans did not pay the gold in time as agreed, but delayed the payment of the check. The Russian traitor was later killed mysteriously. One reason for Americans to pay the bill is that Russia sent an ocean-going fleet to American waters to rescue the United States, at the expense of manpower and material resources. America didn't pay anything at that time. When the Russians retreated from Alaska, they hunted wild offshore animals, claiming that the fjord was red with blood.

Law and Government The capital of Alaska is Juno. Alaska has two senators and a representative. At present, the governor and all members of the state are Republicans.

Geography Alaska has a vast territory and the longest coastline. One of the most famous proverbs in America is "If Alaska is cut in half, then Texas is the third largest state". The Rocky Mountains extend here, forming the highest peak in North America, running through the south-central region from east to west, then turning to southwest and inserting into the sea, forming the Aleutian Islands. The north is slightly lower, bordering on the Arctic Ocean. Because of the high mountains, the south is relatively warm. In fact, many people don't accept the Chinese translation of the highest peak in North America into McKinley Peak because it is a person's name. According to the local custom in Alaska, it should be called Denari Peak, which means the highest peak. Alaska has the best hunting and fishing places in the world. The number of national parks is the largest in the United States. Brooks Mountains is an important mountain range in Alaska.
