What was the first type of Brazilian government after independence

Found this off of google, "After more than three hundred years of Portuguese rule, Brazil became independent in 1822. It first adopted a monarchical system until 1889, when a republic was established. Since 1889, the country has had several forms of government, including state autonomy and centralization, authoritarianism, and democracy."

in my opinion, ap calculus was the most difficult. i often struggled with it a lot. however, i have gotten a lot better.
