In 1961, while in a trip to Mexico after taking office as president, João Goulart fell severely ill, and it was later discovered that he had a heart attack. It wasn't exactly a surprise to Goulart, as he always suffered from cardiac problems and his habits (such as smoking and drinking) had been taking a major toll on his health. But what if he actually died in September 1961? Who would succeed him and how would that affect Brazilian politics in the 1960s?
