What is humanism and how is the concept connected to the Renaissance?

Renaissance humanism was a revival in the study of classical antiquity, at first in Italy and then spreading across Western Europe in the 14th, 15th, and 16th centuries. During the Renaissance period most humanists were religious, so their concern was to "purify and renew Christianity," not to do away with it.

Explanation:

2686-2181 bce-- "egyptian civilization developed along the nile river in large part because the river’s annual flooding ensured reliable, rich soil for growing crops."

1069-664 bce-- "ancient egyptians developed wide-reaching trade networks along the nile, in the red sea, and in the near east."

islamic religious leaders have traditionally been people who, as part of the clerisy, mosque, or government, performed a prominent role within their community or nation. however, in the modern contexts of muslims minorities in non-muslim countries as well as secularised muslim states like turkey, indonesia and bangladesh, religious leadership may take a variety of non-formal shapes.

compared to religious leaders/clerics of the other abrahamic faiths, islamic clergy are said to resemble rabbis and not priests. unlike catholic priests they do not "serve as intermediaries between mankind and god",[1] have "process of ordination",[2] or "sacramental functions",[1] but instead serve as "exemplars, teachers, judges, and community leaders," providing religious rules to the pious on "even the most minor and private" matters.[1]
