Today in history:

Also on this date:

In 1492, King Ferdinand and Queen Isabella of Spain issued the Alhambra Decree, an edict expelling Jews from Spanish soil, except those willing to convert to Christianity.

In 1854, Japan and the United States signed the Treaty of Kanagawa, which opened two Japanese ports to American vessels and marked the beginning of Japan’s transition away from isolationism.

In 1889, the Eiffel Tower in Paris opened for dignitaries; at 1,024 feet, it was the world’s tallest building (the tower would open to the public the following May).
