In what year was Tchaikovsky's 1812 Overture composed?

Tchaikovsky's "1812 Overture" was composed in 1880. The title of the piece might be misleading, as it refers to the historical event of Napoleon's unsuccessful invasion of Russia in 1812. However, Tchaikovsky composed the overture to commemorate the 70th anniversary of that event. It is a grand and celebratory composition that includes cannons and church bells, reflecting the victory of the Russian army against the French invaders.
