Main article: African-American culture 2003 Kwanzaa celebration with its founder, Maulana Karenga, and others
African Americans make up about 12% of the U.S. population. While some customs have come from abroad, many of the customs were developed inside the United States. Kwanzaa, for example, is a custom that has greatly influenced American culture originating from the turbulent 1960s.[104] Most of the newer holidays revolve around a particular civil rights activist and have recently gained attention from city and state-level governments. At the federal level, there are only three national holidays named for a person, and one of those honors 20th century African American Martin Luther King Jr.; the other two are Washington's Birthday (for George Washington, a major Founding Father of the United States), and Columbus Day (for Italian Christopher Columbus's European discovery of the Americas in 1492).
