The first Moravians to come to North America were August Gottlieb Spangenberg and Wenzel Neisser, who accompanied a group of persecuted Schwenkfelders to Pennsylvania in 1735 at Zinzendorf's direction. The first, and unsuccessful, attempt to found a Moravian community in North America was in Savannah Georgia that also began in 1735; it collapsed because of internal discord, and government pressure for Moravians to serve in the militia in defense against Spanish raids from Florida (1740, the so-called "War of Jenkins' Ear").
