The Alaska Purchase is the name of a transaction between the United States and the Russian Empire. Where the United States bought Alaska  from Russia in 1867. It was the Russian diplomat Eduard de Stoeckl and US Secretary of State William H. Seward who negotiated the deal.

Russia had financial problems and feared a war with Britain. They were afraid they could lose Alaska without getting anything left for it. Therefore, Alexander II of Russia decided that Alaska should be sold. He thus instructed Baron Eduard de Stoeckl to start negotiations with the Americans. Negotiations began in early March 1867.   The hearing resulted in the treaty being signed on March 30, 1867 with a purchase price set at $ 7.2 million ($ 4.74 per square mile).
