Great Cathedrals

I wonder about the cathedrals in Britain and Europe. They all seemed to have been built about the same period. What inspired them? Who paid for them ? How could they be designed to remain upright in bad weather? Who built them? Are any names known? How ddid they haul the stones up so high? I have been in several and I stand in awe.
