I have not much to offer but some conditions could be vague and confusing for some players so I made some simple guide for it. Hope this helps. I'll omit some trivial ones like mission since that's more like strategy than a condition explaining.
Other Tropico 6 Guides:
The Governator: Remain in colonial era for 30 years.
Play in sandbox, fulfill crown quest and extend your term over and over again. It is not achievable in mission.(At least in mission 1). You can check the time passed by clicking the palace and selecting the statistics tab.
Double Trouble: Have two faction escalations at the same time.
Worsen your relationship with a faction and they'll send you a ultimatum. Refuse it and suffer their curse. Get curse from two factions within a short time and you're good to go.
Sublime Subliminal Supreme: Have 90% of all Tropicans support the same faction.
Propaganda through Newspaper, Radio, TV and high school. Secretly kill all opposing faction's citizens. I achieved this in modern era so I'm not sure whether it works on other eras or not.
Don't Panic!: Have a Space Mission end with a special event.
You can launch rockets in 'Space Program' facility. Sometimes an event pops up on the ship's return. Event pops up and Penultimo talks about space obelisk. I've earned it during mission within 10 tries but some say it takes more than 1000 launches to get this one.
One Does Not Simply Stage A Coup: Survive a military coup.
Ignore militarists' ultimatum. Anger them with some constitution and edict then finish them off by building lots of embassy.
My Ways: End 50 protests by force or by bribing the protesters across all games.
Tropicans hold protest very rarely and become rebels or guerrillas instead. I've seen only 1 natural protest during my 30 hour like play.
However you can anger environmentalists and their escalation is the mass protest. I don't know whether it's intended or not but most of the time those protesters doesn't appear and protest ends as soon as it began. However if you're lucky they'll appear at each mining, power plant and industry buildings. You can deal with them by clicking the megaphone icon. So trigger environmentalist escalation with actual protest few times and bribe all of them.
