The collection contains a data set of tweets collected from the Twitter microblogging and social networking service regarding anti-government protests in Cuba and the diaspora that began in July 2021. According to Reuters, Cubans across the the island gathered in the streets chanting "freedom" and calling for President Miguel Díaz-Canel to step down from office. The Cuban police responded with violence against protestors. The protests took place in the context of surging coronavirus infections, a weakened economy, shortage of basic goods, and curtailing of civil liberties. Many Cubans in the diaspora rallied in support of the protestors, with some calling for U.S. intervention in Cuba. The Cuban government blamed the country's economic condition on the U.S. embargo against Cuba, and claimed protestors were being manipulated by U.S.-based social media campaigns.
