(All of those PODs are Brazilian):
-Portugal allows Brazil to have manufacturing centers (No Alvará de 1785), Brazil develops small industries by the early 19th century
-The Inconfidência Mineira succeeds. Minas Gerais annexes São Paulo and Espírito Santo and develops small industries
-The Strangford Treaty never exists
-The Portuguese court moves to Brazil earlier, maybe after a Spanish victory in the Fantastic War
-Napoleon wins the war and the court remains in Brazil
-José Bonifácio de Andrada writes the 1823 Constitution and Brazil wins the Cisplatine War
-Alternatively there's never a Cisplatine War in the first place, and the Confederation of the Equator doesn't come into existence, giving more credence to the Royal Family and its proposals for slavery and industry
-The Proclamation of the Republic fails and Isabel, with her proposals for land redistribution, takes the throne following Pedro II's death
-Floriano Peixoto and his military partners are able to secure power in the young Republic. Instead of becoming a country run by oligarchical rural elites, it is run by the Military (Which favored industrialization)
-Alternatively, just have the Great Depression happen earlier, allowing for a Vargas-like figure to take power and promote industrialization
-Avoid the 1964 coup, Brazil is a semi-stable democracy which naturally develops industry and is not controlled directly by rural oligarchies like in the dictatorship
I want to talk about more recent PODs but it would slip into current politics so I'm refraining from doing so
