Christian Michelsen, Norwegian businessman and politician, 1st Prime Minister of Norway (died 1925)

Peter Christian Hersleb Kjerschow Michelsen, better known as Christian Michelsen, was a Norwegian shipping magnate and statesman. He was the first prime minister of independent Norway from 1905 to 1907. Michelsen is most known for his central role in the dissolution of the union between Norway and Sweden in 1905, and was one of Norway's most influential politicians of his time.

The prime minister of Norway is the head of government and chief executive of Norway. The prime minister and Cabinet are collectively accountable for their policies and actions to the monarch, to the Storting, to their political party, and ultimately the electorate. In practice, since it is nearly impossible for a government to stay in office against the will of the Storting, the prime minister is primarily answerable to the Storting. The prime minister is almost always the leader of the majority party in the Storting, or the leader of the senior partner in the governing coalition.
