Although it may have been known earlier, Danish player Martin Severin From essayed the gambit in the Paris 1867 tournament and he is usually given credit for the opening. The Danish Gambit was popular with masters of the attack including Alekhine, Marshall, Blackburne, and Mieses, but as more defensive lines for Black were discovered and improved, it lost favor in the 1920s. Today it is rarely played in top-level chess.
