What is Conservative Judaism?
In general, unlike Orthodox Judaism, the Conservative branch of the Jewish religion is based in the Conservative movement. The movement is not centralized, and hence force it is divided into local branches (For example, Israel and England's movement's are called “Masorti”, which means traditional in Hebrew), that can hold different halachic opinions.
Essentially, the conservative movement differs from orthodox Judaism by believing in changing halacha to suite the modern world, even at the cost of making drastic changes that do not take after most rabbis over the ages. On the other hand, it differs from Reform Judaism by accepting halacha as the structure of the religion, and working within it's framework.
