Brazilian Army Day, observed in Brazil every April 19, commemorates the First Battle of Guararapes, fought on this date in 1648 during the Dutch-Portuguese War. This battle marked a significant Portuguese victory and involved the participation of Brazilian Colonial Forces, leading to the establishment of the day as an official holiday for the Brazilian Army. The Brazilian Army, in its modern form, was created during the War of Independence in the early 1820s and currently comprises about 220,000 active personnel and over 1,800,000 reserves. The day is celebrated with various events across the country, highlighting the importance of the Brazilian Armed Forces and the patriotic spirit of the nation. Additionally, Brazilians also observe Soldier's Day on August 25.
