The Los Angeles Dodgers have a complex history, with their move to Los Angeles involved the displacement of mostly Mexican-American families from Chavez Ravine and the team's arrival of Fernando Valenzuela in 1981 strengthening its Latino fanbase. The stadium was built on land where families, mostly Mexican, were uprooted from their homes in the name of progress. The team's fans are an ethnic melting pot, with many celebrating different cultures at Heritage Nights. The Dodgers have also hosted seven such nights each this season. As America's 250th anniversary approaches, the team provides a powerful lens through which to view the country's history, particularly on social migration, civil rights and immigration.
