How did fidel castro's relationship with the us worsen as time went on?

Fidel Castro made the relationship between Cuba and the US very weak when he came into power. He decided to strengthen his relations with the Soviet Union and put high taxes on US imports. This lead to the US cutting all ties with Cuba

one of the main reasons was definitely slavery. back in 1861, republican abraham lincoln was elected and ended up being a major influence in the slavery business. slavery greatly affected the texas economy because back in 1845 during the annexation of texas, slaves became a big part of the texas population. many texans that were in favor of the secession influenced groups through party ties.
