Hearts of Iron IV has 92 different achievements, all using the Steam achievements mechanics. Achievements have no in-game effects; the achievement just pops up in-game, and is then added to the player's Steam profile. It is possible to see the achievements sorted by the percentage of users that managed to complete each achievement by going to the game's global achievements at Steam.
The difficulty of each achievement varies; some achievements are very easy (e.g. joining a faction), while some are more difficult (e.g. invading Spain as Mexico). The below list groups the various achievements by a difficulty level as assessed by the wiki editors (uncategorized - UC - achievements haven't been assessed yet).
Achievements can only be gained in single-player Ironman games, with the 1936 start, on regular or veteran difficulty. (Can be earned in Elite difficulty since 1.5) They can be earned while playing older versions of the game as long as said achievements were present in that version. They can also be earned with Historical AI Focuses set to off. They are also still available in games which run past the end game screen in 1948 or later.
It is not possible to gain achievements if the checksum has been changed - either by tampering with game files, or by running the game using mods that affect gameplay mechanics (graphical mods do not affect checksum), or a corrupted installation.
List of achievements
The "Notes" column lists helpful short tips/strategies.
The "Ver" column indicates in which version a certain achievement was added. Achievements cannot be earned prior to the version they were added in.
The "DI" column is for difficulty as assessed by wiki editors. VE = Very Easy, E = Easy, M = Medium, H = Hard, VH = Very Hard, I = Insane, UC = Uncategorized.

Make sure that you took as many coastal provinces as you can. After that concentrate on building naval dockyards and make sure that you researched Modern Ship Torpedo Launcher technology. If everything done correctly, you can get this achievement by 1942.

|Playing as either:||Try rapidly puppeting the other three as Sweden and forming a faction with Spain before the third war ends.
Option 2: Go Fascist / Communist ASAP (before 1937). Justify and declare war on Norway/Denmark/Finland in that order. Take all but one province in each peace deal and puppet them. If WT goes above 25%, cancel your justifications b/c France/Britain will almost certainly guarantee. Boost fascist/communist popularity and stage a coup in either Aland (for Finland) or Faroe (for Denmark). They should be able to survive. When WT hits 50%, invite the rebels into your faction.
|Playing as Australia||Control the state Istanbul (341)||The easiest strategy is to join the Comintern and attack Turkey from the USSR. If in the Allies, simple occupation will not work due to Greece having cores on Istanbul.||1.0||M|

Can be done by playing UK as they start with many releasable nations (which can be released as puppets). Turn fascist as soon as possible, disband the Allies, declare war on the US ASAP, France will most likely join them. Capitulate the US first and then focus on France. Make sure to puppet parts of both nations (these puppets can have just 1 province, they are of no use anyway). After that World War II will be divided into few smaller wars. Join Axis and join their wars. Since puppet cost less war score in peace conference you should be able to snipe a few puppets.

Hidden requirement for Installed an American monarchy
|Playing as China||Japan was forced to sue for peace after losing all of Manchuria and Korea||Do not accept cooperation with Communist China until the Japanese are about to attack. Then, form the Chinese United Front and accept all invites. Quickly rush to Korea and push them off the continent. After they have offered peace, accept it, and kick Communist China from your faction. Declare on them and annex them as soon as possible, before they start war against you. Do the same with the other faction members, leaving Sinkiang for last. Dismantle the faction, declare war on the Soviet Union after Germany is pushing east. Join axis. They will be easy to capitulate with all their forces in the west. Take as much territory and then join their war against the allies.||1.5||H|
|Playing as Poland||Country flag POL_vojtek_commander is set||Vojtek is a special commander that appears with the Polish event "Wojtek Never Drops A Crate".||1.0||H|

Place Divisions on the Maginot and around Northern and Central France where the civil war spawns. As soon as war starts with Germany, Capitulate the civil war first and push into Germany. Once Germany capitulates, annex all. Then follow the focus tree until Little Entente.||1.0||H|

|Playing as Sweden|| Is Sweden
As Romania, make it to 1942 with all the states you started it with and control either Moscow or Berlin.
|Playing as Romania||
|All existing nations are fascist||
|Playing as United Kingdom||The straightforward, but boring and slow, approach is to defeat the Axis, then go to war with the Comintern and defeat them (note that the PRC will declare war on China one year after the end of the war with Japan, so you can use the focus to get China democratic and add them to the Allies before that war starts) - this should add lots of countries to the Allies, and then trigger coups everywhere you can. Once there's been a civil war, the winner has created world tension and you can justify against them. It takes a very long time, and, once you've won WWII, it's obviously going to work eventually, so it's very boring.||1.0||H|
|Playing as Germany|| Control the states:
|Playing as Denmark||Use a naval invasion to the two provinces adjacent to Stockholm, but leave one division in Copenhagen with land forts to defend the strait.||1.0||H|

To gain warscore against them, ask Germany for military access and put your troops on their front line. Alternatively, try to naval invade Soviet's far east front and capture a few victory point provinces. In patch 1.6.0, German is very likely crush the Soviets without trouble in one or two years. During the peace conference, the Fascists will focusing on grabbing land, so it is possible to puppet the Soviet Union.
|Playing as Mexico|| Control the states:
||Rush Fascist and justify wargoal on Philippines, if you try to justify on a major country like the United States world tension will skyrocket but because Philippines is a puppet the US will automatically join when you declare war upon them. With this you should have no problem overrunning the country with either infantry or cavalry. Try to poke holes in the US line as they will have a tough time manning a long border and encircle their troops. They will have no way to real way to grow their military until they remove isolation so it should be trivial to win this way.||1.0||H|

Annexing the US may help industrially and the Send in the Zombies focus may help with recruitable population. If Iceland gets released, it may be necessary to justify against them. Try to take the UK before Germany or Italy tries a naval invasion. If the peace conference triggers before the achievement does, try to annex all of Great Britain as the other Axis members may take required territory. It may be advisable to create a faction with Mexico instead of joining the Axis to make it harder for Germany to take British states in the peace conference.||1.3||VH|

From there it is only a matter of time until your fleet sinks the Hood for the achievement.
