"Tarzan, Lord of the Jungle" is the eleventh book of the enormously popular twenty-four volume series of Tarzan novels by adventure fiction writer Edgar Rice Burroughs.

In this chapter of the Tarzan saga, Tarzan encounters the ancestors of a group of knights and crusaders who ran astray on their way to the Holy Land centuries earlier. Their modern-day descendants still maintain a culture based on their Medieval predecessors, but have broken into two warring factions with which Tarzan must contend.

Tarzan is among the most popular fictional characters in all of literature and his tales have been adapted into dozens of animated and live-action films as well as television and radio series and comic books.

"Tarzan, Lord of the Jungle" is presented here in its original and unabridged format.
