Peregrin Took was just in his tweens when he announced his intention to accompany his cousin Frodo Baggins on his quest. Pippin's youth and curious nature got him into trouble on occasion, but his steadfast friendship and unquenchable cheerfulness helped carry him and his companions through the darkest times. During the quest, he grew up quickly and became an important member of the Fellowship and a Knight of Gondor.

Pippin was born in 2990, the only son of Paladin Took and Eglantine Banks Took. Pippin's father farmed the lands around Whitwell near Tuckborough, and he also held the title Thain Paladin II. The Thain was master of the Shire-moot and captain of the Shire-muster and the Hobbitry-in-arms. These titles had become largely nominal dignities, but the Thain was accorded a special respect among Hobbits. As the Thain's heir, Pippin was a young gentlehobbit of rank and wealth.

In addition to their wealth and social standing, the Tooks were also noteworthy for the adventurous streak that ran in the family. This quality was apparent in Pippin, who, along with his close friend Merry Brandybuck and Frodo's gardener Sam Gamgee, conspired to uncover the cause of Frodo's mysterious behavior in the spring and summer of 3018. But it was more than adventurousness that prompted Pippin to decide to leave the Shire with Frodo; friendship and loyalty were equal factors.
