Bogging down?

As several have pointed out, excommunication is an explicit invitation by the Pope to have everyone attack you to get into his good graces. So not only does it give them a free rein to try to seize your territories, but it also increases their papal standing. You need to get out of that status ASAP or yes you will be attacked by the entire Catholic world. Unfortunately, the only ways I know of are 1) kill the Pope or 2) have your faction leader die. Fighting the Pope's armies emphatically will not convince him to lift the ban of excommunication; if anything it makes it worse, unless you manage to catch him heading a stack of troops and kill him. So you're left with assassins (dubious) or sending your faction leader off to conquer the Mongols and Timurids barehanded.

You can bribe the pope aswell to get reconsilled, i think the most you need to pay him is 10000 and thats only if your standing with him is really bad.

What also might be happening is that one faction that you are at war with decides to ally with 6 other factions that never really liked you too much in the first place so they will attack you. Now it is nearly impossibe to get a ceasfire since all of your enemies will be allied and they won't want to abandon their allies. This happened to me when I was playing as Venice. The HRE signed an alliance with Hungary, Byzantine, Turks, Sicily, French, Spain, Scots, and Poland. All of them declared war on me except for the scots who cant really attack me. I have been destroying their alliance one faction at a time. Have killed Hungary, Byzantine, and Sicily with Turks almost dead

I know 10000 is not a fixed number. I paid 16200 tribute for two turns for reconciliation. I was dubious about emptying savings but
1. I got reconciliation.
2. It put my Popeometer all the way to the top instantly when I had no crosses to start with.
