Hello,

Figured I would post some research I've one for another area. I know that you're probably too busy with fixing 10.0 to pay much attention to this now. But still I hope it helps in the future. This is probably a little too detailed and needs some cuts but I think it's a decent first draft.

Notes on Associated States:

A number of territories chose throughout our period to "Associate" themselves to the Swiss Confederation. This was a form of close alliance with either the Confederation as a whole or with one or more individual cantons within the confederation. While this certainly did obligate the Confederation (or members within it) to come to the defense of Associates during times of war it did not seem to give the Confederation any substantial power over the internal affairs of the Associate. Currently this is represented in game by having the associates be a part of Switzerland, ie by side-stepping the problem entirely. However, I don't think that this relationship would be well represented by a normal alliance either. I think that the way I would go about it (ie the least-worst way I can think of) is to have the associated states as a special form of vassal to the SWI tag similarly to what you did for the Papal States in relation to the Papacy. So that Switzerland would be obligated to fight alongside its Associates during defensive wars, and vice-versa, but that it would entirely optional for the Associates to join an offensive war by Switzerland, and vice-versa. Also the Associated states should not give any tribute, taxes, manpower, etc to Switzerland. And maybe there could be some late-game decision/event that would allow Switzerland to incorporate them. It would have to be late game because most of the Associated territories didn't join Switzerland until either the Helvetic Republic (Napoleonic puppet government) or the Treaty of Vienna at the end of the Napoleonic Wars.

Provinces:

1: Geneva; Already exists in BT 10.0. I would recommend however, that it become its own tag as a vassal to Savoy. It was effectively autonomous from the dukes of Savoy, although they tried very hard to change this. It was first granted autonomy in 1387 and its local notables pushed for more and more autonomy over the years. There was a great deal of very dramatic back and forth political battles between the Dukes of Savoy and the Grand Council in Geneva. In 1526 after gaining full independence from Savoy the city-state Associated with the Swiss Confederation but did not actually join the confederation fully into 1814/1815 at the Congress of Vienna. Was a major center of the reformation (John Calvin).

2: Vaud: Already exists in BT 10.0. Was a territory of the Dukes of Savoy in 1444 up until its conquest by Bern (a member of the Swiss Confederation) in 1536. Stayed in Switzerland for the rest of the period except for some brief periods during the Napoleonic Wars. Converted to the Reformed Church during the Reformation.
https://en.wikipedia.org/wiki/Canton_of_Vaud

3: Fribourg: Part of Vaud province in BT 10.0. I argue that it should instead be an independent tag that is a vassal to Austria. The Habsburgs had been effectively the overlords of Fribourg since they bought the territory in 1277. The territory was effectively autonomous however, with its own armies and elected government. In 1452 the Habsburgs ceded the city to the Dukes of Savoy. The city would gain full independence in 1477, became an Imperial City in 1478, and then join the Swiss Confederation in 1481. Remained Catholic during the Reformation.

4: Neuchatel: One of the more interesting parts of Switzerland. Spent most of the period under the rule of various distant dynasties; First the Lords of Freiburg, then to the House of Baden, then to la duchess de Longueville, then to the Swiss Confederation during a decade-and-a-half occupation, then back to the duchess de Longueville, and then finally to the Hohenzollerns of Prussia. It remained in Hohenzollern hands (under a personal union) until 1848 when a Republic was declared. Although it was briefly occupied during the Napoleonic Wars and Frederick Wilhelm III did allow it to join the Swiss Confederation as a sort of Condominium. Converted to the Reformed Church during the Reformation. Anyway, it is a very small province and probably won't make it into the game but if it does I think it should be an independent tag under some combination of personal unions with whatever tags best represent these various dynasties.

5: Jura: Jura represents the western half(ish) of the territories of the Prince-Bishopric of Basel. This was predominately French and Catholic unlike the German & (Eventually) Protestant eastern half. It also represents the territory that remained under the control of the Prince-Bishophric after the Reformation drove it out the newly protestant territory.

6: Basel: The other half of the territories of the Prince-Bishophric of Basel. Home of a major university and an important ecclesiastic center for much of western Europe. Also a major center of book publishing after the invention of the printing press. Converted to the Reformed Church during the Reformation.

7: Aargau: A territory conquered by the Swiss Confederation from the Habsburgs 1415. Was a important grain growing region for the Confederation. Eventually fully integrated into the Confederation as a canton in its own right. Mostly converted to the Reformed Church during the Reformation.
https://en.wikipedia.org/wiki/Canton_of_Aargau

8: Lucerne: A independent city state that in 1332 joined the Swiss Confederation as its 4th member. The first important town to join the confederation. Stayed in Swiss hands throughout our period (excepting Napoleon). Remained Catholic during the Reformation.

https://en.wikipedia.org/wiki/Lucerne

9: Bern: Same as in BT 10.0. Probably the most important member of the Swiss Confederation. Certainly the largest and most militarily powerful. Joined the confederation in 1353. Became the capital of the new Swiss Federation in 1848. Converted to the Reformed Church during the Reformation.
https://en.wikipedia.org/wiki/Bern

10: Zurich: One of the richest cities in Switzerland and occasional capital of the Swiss Confederation. Joined the Confederation in 1351. Converted to the Reformed Church during the Reformation.

11: Thurgau: A holdover of Habsburg rule over much of Switzerland. That dynasty gained this territory in 1264 and held it until 1460 when it was taken by the Swiss Confederation in a war. Eventually Thurgau became a canton in its own right. Mostly converted to the Reformed Church during the Reformation.
https://en.wikipedia.org/wiki/Canton_of_Thurgau

12: St Gallen: Represents the Abbey of St Gall an important religious sight and principality in its own right. Fought both with and alongside the Swiss Confederation and eventually chose to Associate with the Confederation but never joined it. In 1803 the territory formally joined the Swiss Confederation although by that point the Abbey no longer existed as an independent power (although it continued to exist as a purely spiritual institution). Converted to the Reformed Church during the Reformation. I would suggest that this be represented as an independent tag. Admittedly this territory is quite small and should probably be one of the first on the cutting boards if things must be cut.

13: Appenzell: A breakaway territory from the Abbey of St Gall that rebelled in 1401-1405 and joined the Swiss Confederation as a canton in 1411. Stayed in the Switzerland for the rest of our period (excepting Napoleon). Would remain Catholic during the Reformation.

14 & 15: Lower and Upper Valais Respectively: The Valais was the traditional territory of the Bishopric of Sion. However when the Dukes of Savoy claimed that title around 1370 the local independent communities (Zenden) refused to recognize their sovereignty. This kicked decades of intermittent fighting between the forces of the Zenden and the Savoyards which ended up splitting the territory in two. in 1444 these are; a smaller primarily Francophone Lower Valais in the hands of the Dukes of Savoy; and a larger primarily German speaking Upper Valais under the independent Bishop of Sion. Eventually in 1475 the Bishop and Zenden invaded and conquered Lower Valais from the Dukes of Savoy. In 1529 the united Valais associated with the Swiss Confederation. Would remain Catholic during the Reformation.

16, 17, 18: The Graubunden, or Grey Leagues, an alliance of three individual leagues, the League of God's House, the Grey League, and the League of Ten Jurisdictions respectively. I carved up the Graubunden province to represent each of these three as their own province. The League of God's House formed in 1367 to fight off the influence of the Bishopric of Chur and the House of Habsburg. The Grey League formed in 1395 to put an end to endless intermittent violence between local petty lords. The League of Ten Jurisdictions formed in 1436 after the death of the Count of Tonnenburg (who ruled the area) without an heir. These three Leagues formed a broader alliance in 1471. They would not form a more formal, stronger union until 1524. The Three Leagues together would Associate with the Swiss Confederation in 1497. Rough religious parity between Catholics and Reformed after the Reformation. So technically the Graubunden tag shouldn't exist in 1444 and instead each of these Leagues should (historically) be its own separate tag until either 1471 or 1524. However, I would understand if you didn't want to do that. They would be very small and insignificant.

22: Glarus: Joined the Swiss Confederation in 1352 after gaining independence from the Habsburgs. Very poor and lightly populated. Mostly converted to the Reformed Church during the Reformation, Zwingli preached here.

23: Ticino: Same as you made it after the Italy overhaul in BT 10.0!
