Freemasonry bears the imprint of the society in which it exists, and Freemasonry in North America is no exception. While keeping close ties to French lodges until 1913, American Freemasonry was also deeply influenced by the experiences of many early American political leaders, leading to distinctive differences from European lodges. The author investigates the racial split in American Freemasonry between black lodges and white and how, unlike French lodges, women are ineligible to become Masons in the U.S. He examines how American Freemasonry has remained deeply religious across the centuries and forbids discussion of religious or social issues in its lodges, unlike some branches of French Freemasonry, which removed belief in God as a prerequisite for membership in 1877 and whose lodges operate in some respects as philosophical debating societies. Revealing the factors that have resulted in shrinking Masonic enrollment in America, the author explores the revitalization work done by the Grand Lodge of California and sounds the call to make Freemasonry and its principles relevant to America once again.
