In June of 1977, U.S. Representatives Frank Horton of New York and Norman Mineta of California introduced a resolution to establish Asian-American Pacific Heritage Week, to be celebrated each year at the beginning of May. Senators Daniel Inouye and Spark Matsunaga of Hawaii introduced similar legislation in the Senate. The following year, President Jimmy Carter signed into law a joint resolution to establish the annual event, and the first celebration took place in May of 1979.
In 1992, the month of May was designated by President George H. W. Bush as Asian-American Pacific Islander Heritage Month. The annual celebration honors the many contributions and accomplishments of Asian Americans, Pacific Islander Americans, and Native Hawaiians.
