The Grand Marquis is the upscale version of the Crown Vic. Marketing targeted toward those who think the Grand Marquis is a fancier car (cosmetically it is).

EVERY car maker does that.

It was all marketing and using most of the same parts.

The Grand Marquis is a Mercury and it was common for Ford as well as General Motors to make very similar if not identical cars and sell them as different names under their different brands.

Because one was a Ford brand of car and the other was a Lincoln Mercury brand of car.
Same company, but Lincolns are marketed to more upscale clients.
