Jackie Robinson was a groundbreaking American baseball player who made history in 1947 by becoming the first African American to play in Major League Baseball (MLB) in the modern era. He played for the Brooklyn Dodgers and was known for his exceptional skills, speed, and courage in facing racial discrimination both on and off the field. Robinson's impact extended beyond baseball; he became a symbol of the civil rights movement, advocating for equality and social justice. His legacy is celebrated every year on Jackie Robinson Day, when players across MLB wear his iconic number 42 in honor of his contributions to the sport and society.
