Page "Talmud" Paragraph 34

The influence of the Babylonian Talmud has been far greater than that of the Yerushalmi.

In the main, this is because the influence and prestige of the Jewish community of Israel steadily declined in contrast with the Babylonian community in the years after the redaction of the Talmud and continuing until the Gaonic era.

Furthermore, the editing of the Babylonian Talmud was superior to that of the Jerusalem version, making it more accessible and readily usable.

According to Maimonides ( whose life began almost a hundred years after the end of the Gaonic era ), all Jewish communities during the Gaonic era formally accepted the Babylonian Talmud as binding upon themselves, and modern Jewish practice follows the Babylonian Talmud's conclusions on all areas in which the two Talmuds conflict.
