Lititz /lɨtɪts/ is a borough in Lancaster County, Pennsylvania, 6 miles (approximately 10 km) north of the city of Lancaster.
Lititz was founded by members of the Moravian Church in 1756, and was named after a castle (mentioned form of name is German; Czech name of this castle is Litice) in Bohemia near the village of Kunvald where the ancient Bohemian Brethren's Church had been founded in 1457. The roots of the Moravian Brethren's Church date back to the ancient Bohemian Brethren's Church.
For a century, only Moravians were permitted to live in Lititz. Until the middle of the 19th century, only members of the congregation could own houses; others were required to lease. The lease-system was abolished in 1855, just five years before the beginning of the Civil War. More information can be found in the book A Brief History of Lititz Pennsylvania by Mary Augusta Huevener, published in 1947.
