My vassals hate me and i am very confused

[BobLou]

I started a campaign as Munster and now own the majority of England Iceland and Ireland the problem is my leader just died and now all my vassals hate me. Like -100 nearly every one. I think its because i have had a short reign and my culture group so what should i do

First of all, have a look at modifiers so you can see what can be done to improve the situation, short reign alone is not that big. It's very important that your Spymaster doesn't hate you as well, otherwise it's a matter of time before the new ruler will meet the previous one.

Get some alliances ASAP, at least one outside with somebody more or less your size and one with a powerful vassal.

See if you can create some new Titles, you may be able to give some of them away and then transfer some vassals around as well, so you'll have less of them being able to join Factions and some good opinion boosts.

Probably you expanded too fast. Expect to be de-expanded just as quickly.

Bribes, sway, romance, seduce, befriend if you can. Murder, imprison, fabricate hooks if you can't. Pay closest attention to the Factions tab!

In the long run, you will want to make sure your Councillors are as happy as possible, especially your Spymaster. Set your diplomatic focus on Domestic Affairs and have your Councillors work on quelling religious, order, and cultural unrest. That stuff takes a long time, so the sooner you start the better. For the love of all that is holy, avoid war for as long as possible.

If you can, give out titles. If you can't, consider relaxing vassal contracts an/or lowering crown authority. Those aren't good things to let go of, but if it's that or your head...

This is what happens to people who think this game is a race to paint the map. There is alot more to the game.
