Missions are tasks that can be completed for certain bonuses and rewards ranging from claims and pops to special modifiers or even gaining or releasing new subject nations, providing optional direction for expansion and development as well as flavour and a historically-based narrative for countries that have more unique missions. Some missions, especially timed ones, can trigger events and some can lead to long and complex event chains with many different possible options and outcomes. All missions are structured as part of a mission tree, with prerequisites that enforce a natural flow through the tasks or mutually exclusive paths to force the country to choose between different options as well as optional branches that can be completed for additional bonuses or ignored if it does not the fit the country's current goals. Some mission trees, particularly the generic ones, are highly versatile with the tree structure and task targets dynamically generated to fit the country and region's current circumstances.

National Missions

Nations with unique mission trees at 450 AUC/304 BCE.
Hatched countries do not start with access to national missions, but can gain access to them over the course of the game.

Certain countries have their own dedicated sets of mission trees exploring their culture and history, current situation, and specific ambitions. These are by far the most detailed and fleshed out mission trees, and all require a certain DLC to be enabled in order to appear ingame.

Culture Missions

Culture group with unique mission trees at 450 AUC/304 BCE.
Hatched countries either only have group missions without a particular DLC, do not start with access to the missions but can gain them by becoming independent, expanding, or creating a local formable nation, or potentially have access to multiple group mission trees. Note that this map is not completely comprehensive and it is possible for other countries to gain access to group missions under some circumstances.

Countries of certain culture groups have specific "group" missions, which are available to all countries of the culture group in a specific region or area.

Generic Missions

Main article: Generic missions

There are 3 generic missions available to all countries in the game:

Mechanics

Mission Tasks

Potential

Not all tasks will always appear in the mission tree, particularly for the generic conquest and infrastructure missions. Mission tasks will only appear if their potential conditions are fulfilled, usually corresponding to if the particular branch was selected or if the task is at all relevant. Some tasks are mutually exclusive with each other, with only one out of a possible set ever appearing at a time depending on the exact circumstances (or possibly being chosen randomly). Tasks whose potential are not met do not appear on the mission tree screen and cannot be completed; if they are listed as a prerequisite for another task, this requirement is instead ignored.

Prerequisites

Other than a few starting missions, most tasks have prerequisites that need to be completed before they can be taken or completed, indicated in the interface by an arrow going from the prerequisite to the task that it unlocks. For the purposes of proceeding along the tree, prerequisites also count as completed if they have been bypassed or do not meet their potential (therefore not appearing on the tree at all).

Bypassing

Tasks can be bypassed under certain conditions, usually either the task requirements no longer being possible or relevant or a mutually exclusive task being taken. Bypassed tasks can be easily identified by their statue icon being replaced with a heap of rubble; when bypassed, a task is considered completed for most intents and purposes except that the country does not get the task's rewards.

Completion and Effects

When a mission's requirements are met and its prerequisites have been finished or bypassed, its tile in the mission tree screen will turn from grey to peach and can be taken simply by clicking on it. Most tasks will complete and give their effects immediately, but some missions are timed tasks (indicated by the progress bar at the bottom of the tile) which may take anywhere from a few months to up to two years. Timed tasks may trigger effects when they begin and/or end and frequently have special events that can trigger while they are running as well, and do not count as completed until it has run its entire course. A few timed missions can fail under certain circumstances, which stops the progress timer may prevent the country from retaking the task, blocking them from going down that path.

Mission Trees

Generation

While many of the more country-specific mission trees are largely fixed, the more generic ones are more dynamically generated with different branches and tasks as well as the regions, provinces, or nations they target being selected either randomly or based on the country's current circumstances. Some of the higher-level target selection, such as the region target of the generic conquest and infrastructure missions, is done on potential when the mission first appears in the selection screen; this will not be reset unless the mission is taken and completed or aborted, or if the country no longer meets the requirements (and it therefore loses it from its pool) and then somehow regains it. Most of the lower-level target selection, such as the conquest targets for the generic conquest mission is instead done on start, i.e. when the mission is selected and started. Once a mission is generated and started, it will usually not change the composition of its structure or the target of its tasks while running.

Selection

Each country can only have a single mission tree active at a time. When first starting the game, or after completing or aborting a mission tree, the country will be presented between a choice of up to 3 possible mission trees to take, drawn from the pool of mission trees for which it meets the requirements; nation or culture-specific missions are more likely to appear than generic ones, though it is rare that a country will be eligible for more than 3 mission trees at a time. Each mission can be selected to display a description and a brief overview of the goals of the mission and then started with the Start Mission button. The available missions are redrawn from the pool each time a mission is completed or aborted, making it possible to take and then abort a mission if the desired mission is possible but does not currently appear.

Structure

Most mission trees are structured to have a generally linear flow from top to bottom, with at least some of the missions in each row required to start the ones following, with the final completion tasks at the bottom of the tree. Some have varying degrees of branching where the country may be able to choose from a number of different options and outcomes to focus on, with some being mutually exclusive and bypassing the other possible options. In addition to those required to progress down the tree, there are also often many optional tasks and even entire optional branches that do not need to be completed in order to finish the tree, but may provide extra bonuses if the country takes the additional effort to complete them.

Completion

All mission trees have certain final tasks, usually those at the end of the main branch, that need to be completed before finishing the tree; the remaining tasks can be viewed by hovering over the greyed-out Finish Mission button. Finishing the mission tree can be done at any time after all final tasks are completed be pressing the button, which may also give some additional effects or rewards. Waiting to finish the mission tree, for instance to complete various optional tasks, is allowed. Most mission trees can only be taken once and will disappear from the pool forever once completed, though some are repeatable and can be taken over and over as long as their requirements are met.

Abortion

Mission trees can be aborted at any time using the Abort Mission button, and some missions will also be automatically aborted if the country no longer meets certain requirements, though this is generally rare. Aborting a mission tree will prevent the country from proceeding down any remaining tasks, though most currently collected rewards and modifiers will usually be kept and the country will be allowed to select a new mission tree in the mission selection screen. Some missions, particularly the generic conquest mission, also have a cost to aborting that makes extensive use of mission abortion to get the desired target less viable. Aborted mission trees can usually be restarted from the beginning if the country still meets the requirements, though most have a cooldown of 20 years after aborting before they can be restarted.
