Fidel Castro’s death at age 90 Friday was a moment for millions of Cuban Americans to both celebrate and mourn. Celebrate because the brutal dictator they and their families fled from had finally died; mourn family members who could not wait out Castro’s life in hopes of returning to their homeland.

Whether it was cozying up to the Soviet Union, backing Angolan leftists or exporting his revolution to Venezuela and other Latin American countries, Castro influenced United States policy for more than 60 years. The economic embargo imposed by President John Kennedy in 1962 is still in place today. Cuban migrants get preferential treatment if they make it to the United States.

President Barack Obama visited Cuba earlier this year, marking the resumption of diplomatic relations between the two countries. President-elect Donald Trump warns that could be reversed if Cuba doesn’t make progress on human rights and release political prisoners and fugitives from U.S. law.

Although Castro transferred power to his brother Raúl in 2006, Fidel was still a larger-than-life influence. Now that his life is over, how will generations of Cubans who knew no other leader go forward?
