Before Europeans arrived, the Philadelphia area was home to the Lenape (Delaware) Indians in the village of Shackamaxon. The Lenape are a Native American tribe and First Nations band government. They are also called Delaware Indians and their historical territory was along the Delaware River watershed, western Long Island and the Lower Hudson Valley.[a] Most Lenape were pushed out of their Delaware homeland during the 18th century by expanding European colonies, exacerbated by losses from intertribal conflicts. Lenape communities were weakened by newly introduced diseases, mainly smallpox, and violent conflict with Europeans. Iroquois people occasionally fought the Lenape. Surviving Lenape moved west into the upper Ohio River basin. The American Revolutionary War and United States' independence pushed them further west. In the 1860s, the United States government sent most Lenape remaining in the eastern United States to the Indian Territory (present-day Oklahoma and surrounding territory) under the Indian removal policy. In the 21st century, most Lenape now reside in the US state of Oklahoma, with some communities living also in Wisconsin, Ontario (Canada) and in their traditional homelands.

Where did the Lenape go after being pushed out of the Philidelphia area?
Answer: upper Ohio River basin

Based on earlier transmitted reports, in the year 632, after the demise of Muhammad a number of his companions who knew the Quran by heart were killed in a battle by Musaylimah, the first caliph Abu Bakr (d. 634) decided to collect the book in one volume so that it could be preserved. Zayd ibn Thabit (d. 655) was the person to collect the Quran since "he used to write the Divine Inspiration for Allah's Apostle". Thus, a group of scribes, most importantly Zayd, collected the verses and produced a hand-written manuscript of the complete book. The manuscript according to Zayd remained with Abu Bakr until he died. Zayd's reaction to the task and the difficulties in collecting the Quranic material from parchments, palm-leaf stalks, thin stones and from men who knew it by heart is recorded in earlier narratives. After Abu Bakr, Hafsa bint Umar, Muhammad's widow, was entrusted with the manuscript. In about 650, the third Caliph Uthman ibn Affan (d. 656) began noticing slight differences in pronunciation of the Quran as Islam expanded beyond the Arabian Peninsula into Persia, the Levant, and North Africa. In order to preserve the sanctity of the text, he ordered a committee headed by Zayd to use Abu Bakr's copy and prepare a standard copy of the Quran. Thus, within 20 years of Muhammad's death, the Quran was committed to written form. That text became the model from which copies were made and promulgated throughout the urban centers of the Muslim world, and other versions are believed to have been destroyed. The present form of the Quran text is accepted by Muslim scholars to be the original version compiled by Abu Bakr.

Which caliph decided to preserve the Quran as a single book after some of Muhammad's companions were killed in battle?
Answer: Abu Bakr
