U.S. President Barack Obama declared on Tuesday that he had come to Havana to “bury the last remnant” of the Cold War in the Americas as he spoke directly to the Cuban people in a historic speech broadcast throughout the island nation.

Speaking at Havana’s Grand Theater with Cuban President Raul Castro in attendance in what White House officials touted as a crowning moment of Obama’s visit, Obama said he was there to “extend a hand of friendship.”

Obama’s address marked the final day of his trip, the first by a U.S. president to Cuba in 88 years. His presence in Havana was the culmination of a diplomatic opening that he and Castro announced in December 2014, ending decades of estrangement between Washington and Havana.
