From the early 1800s to the 21st century, Asian and Pacific peoples have played a vital role in the development of the United States and made lasting contributions in all elements of American society. The month of May has been recognized as Asian-Pacific American Heritage Month since 1977.

May Celebration

May was chosen to commemorate the immigration of the first Japanese to the United States on May 7, 1843, and to mark the anniversary of the completion of the transcontinental railroad on May 10, 1869. The majority of the workers who laid the tracks were Chinese immigrants.
