In Mexican history, the War of Independence and the Revolution are two distinct historical periods. The Bicentennial commemorates the beginning of what became the Mexican Independence Movement in 1810. The Centennial celebrates the Mexican Revolution, which began on November 20th, 1910.
It's convenient for students of Mexican history, as it makes it easier to remember when the two movements began.

Happy Revolution Centennial to our Mexican readers !
