Was David's marriage to michal prearragned?

Answer 1

Technically yes.

Saul was trying to marry one of his daughters to David so he could somehow have an advantage over him and somehow that would make the Philistines kill him... (there is no clear reason). David turned down Saul's first daughter, Merab, after he tried to arrange a marriage for them. Saul then figured out that Michal was in LOVE with David, and again tried to have them married. David turned him down again, but Saul wasn't going to give up so easily. He was still trying to get David killed by the Philistines, so he said that David could marry Michal if he could get the foreskins (please don't ask what that is) of a hundred Philistines. So David was finally satisfied with this (an issue with pride and humbleness) and did just that. Only he killed 200 Philistines and brought back 200 foreskins to Saul (yummy). Then David and Michal were married. It said David married Michal to become the king's (Saul's) son-in-law, but it also mentions how much Michal loved David.

1 Samuel 18:27-28

David and his men went out and killed two hundred Philistines. He brought their foreskins and presented the full number to the king so that he might become the king's son-in-law. Then Saul gave him his daughter Michal in marriage. When Saul realized that the LORD was with David and that his daughter Michal loved David,"

So yeah it was prearranged.

Though I feel as though Michal may have asked to marry David after he turned down Merab.
