This whole world is a foreign land
The Data
This is 153 Invasions and Annihilations (which are basically just big Invasions that take up similar kinds of attention/energy while meeting similar needs).
When do Invasions happen?
Or rather, when's the best time to expect them? (You could read this as 'when's the best time to launch one,' but that's more of a faction judgment call.)
Overwhelmingly, the start of the year and the middle of summer.
Have Invasions declined?
Replies per Invasion/Annihilation are stable. The appetite is there.
More importantly, other than spikes associated with a few specific Invasion-focused Major Factions, total Invasion/Annihilation posts have been essentially stable for a decade. Slower lately, but I'll get into some potential factors in a minute.
So why does it look like Invasions have declined? You promised me answers!
Well, like I said, there are spikes. Some of that has to do with faction political/identity factors.
Another possible factor: the aftereffects or diminishing returns of a few very large intense threads. Nobody who crawls out of a 1,200-post thread has any inclination to do it again for a minute.
Another probable factor: the rise of new thread types a few years back.
It's up to faction members and faction leaders whether that's good, bad, or just evolution, baby.

UPDATE: The Junction Hypothesis
Let's take a closer look at Junctions. Everything above involved false starts and dead ends and adding Junctions was more straightforward than I expected.
The data now includes 78 Junctions for an additional 7,858 replies, equivalent to somewhere around one or two million words. (Average posts may be shorter.)
Junctions may be individually smaller than Invasions on average, but they added up to completely change the 'Invasion+' picture of the last few years. In fact, 2024 saw almost as many 'Invasion+' posts as the average of all previous full years, outlier spikes included (4230 vs 4830 for 2014-23). 2024 was an average year. 2025 is also on track to be an average year.
This is 153 Invasions and Annihilations (which are basically just big Invasions that take up similar kinds of attention/energy while meeting similar needs).
- I'm reasonably confident the dataset is complete, but one-third of Invasions don't have the Invasion tag, so some of this was manual.
- This data does not include other types of large competitive thread, like Events or Junctions. That's important for reasons discussed below.
- At a ballpark estimate of 250 words per post, that's over 11 million words — more than the Stormlight Archive, A Song of Ice and Fire, Lord of the Rings, and Wheel of Time put together.
- Nine other planets have seen at least three Invasions or Annihilation attempts: Coruscant, Alderaan, Ziost, Dromund Kaas, Dubrillion, Mon Calamari/Dac, Korriban, Muunilinst, and Tython.
When do Invasions happen?

Overwhelmingly, the start of the year and the middle of summer.
- You can see half the board hit fall and winter final exams on this chart. Actual board activity may not drop then, but nobody wants to be running an Invasion or Annihilation while cramming for Biochemistry 350.

- The GA and Sith had their back-and-forth, and there certainly seems like some mess in the Core Worlds, but largely, it looks to me like Invasions have become kind of piecemeal and without much big-picture impact. I can't blame people if they're feeling like lately, Invasions don't accomplish much for the effort.
- Invasion rules tweaks could be considered by people with way more skin in the game than I have, but at the faction level, there's no Ashlan One-Maw Imperium out there raving for your head. There's no 'democratization of fear.' Shame.

Another possible factor: the aftereffects or diminishing returns of a few very large intense threads. Nobody who crawls out of a 1,200-post thread has any inclination to do it again for a minute.

Another probable factor: the rise of new thread types a few years back.
- First Reply has been a huge outlet, and Junctions and Populates get a lot of attention too. Junctions are interesting because they're diet Invasions: they gave Major Factions a popular, low-barrier, low-stakes way to do a lot of what they'd otherwise be doing through Invasions.
- I don't plan to capture post numbers or per-quarter totals on every single Junction the way I did with Invasions (EDIT: see below for The Junction Hypothesis), but just in terms of number of (often smaller) threads, a chunk of inter-faction energy that used to go into Invasions clearly goes into Junctions now:

It's up to faction members and faction leaders whether that's good, bad, or just evolution, baby.
