Nehar Peḳod (Hebrew: נהר פקוד) was a Babylonian Jewish community in the town of Nehardea. Nehar Pekod was popularized as a center of learning by Rav Hananiah, leading to thousands of Judeans settling in the town after the Bar Kokhba Revolt. Rav Hananiah even tried to establish a bet midrash and a Sanhedrin with the authority to manage and change the Jewish calendar. However, Jewish authorities back in Judea immediately intervened, denouncing the authority of the community. Rav Hananiah died and was buried in Nehar Pekod. The community experienced another era of prominence during the Geonic period when tens of thousands of Surian Jews came to Nehar Pekod to learn. Several notable Sura Gaons were either educated or born in Nehar Pekod, including:[1][2]
By the 9th century, most of the community had immigrated back to Sura.
