Seven months after President Obama announced that the United States would begin normalizing diplomatic relations with Cuba, the Cuban flag is flying in the United States for the first time in 54 years. Large crowds gathered outside the Cuban Embassy in Washington, D.C. as the flag was raised for the first time since 1961. Here’s what went down on this historic day:

That’s the same flag that was lowered in on January 3, 1961, when the US cut off diplomatic ties with Cuba.

Others celebrated with a cigar.
