Overview
This forum post is an abridged transcription of the 1812 Overture rules document (version 1.5). It contains the complete rules, though additional examples and clarifications can be found in the Full Rules PDF.

If you would like to know more about the background of this variant and its development, I have an article in Issue 135 of Diplomacy World that you might find interesting.

Except as described below, standard rules of Diplomacy apply.

1812 Overture is a variant set in the Napoleonic era, with emphasis on:
  • The "War of 1812" between the United States and Britain/Canada
  • The "Patriotic War of 1812" between France and Russia
  • The "Peninsular War" between France, Britain, Portugal, and Spain
  • Other conflicts and political instability circa 1808-1815.

There are twelve powers on the map, with each of six players controlling two of them (similar to Versailles). There are two continents (theatres), North America (NA) and Europe (EU), connected by the Atlantic and Arctic oceans. Five of the six players start in each theatre.

The game ends when a player conquers 18 SCs (total), with at least 12 of those SCs located in the same continent. Two players can simultaneously achieve these goals as well for a double-win.
Unlike prior versions of this variant, the 12 SCs you capture in a single continent do not have to be controlled by a single power.

Maps
See below for map images.

Starting Year
The game does not start in 1812, but rather starts in Spring 1811, since an "overture" comes before a performance.

12 Powers, 6 Players
Six powers in EU. Six powers in NA.
Three players get attached (preset) pairs, three get detached (random or auctioned) EU/NA pairs.
Napoleon gets two powers in EU. USA gets two in NA.
Everybody else has one power in each continent.

Victory Conditions
The game ends in a Solo Win, a Double Win, or a draw.

  • Solo Win: 18 & 12
    • 18: 18+ SCs (total of both powers)
    • 12: 12+ in one continent (total of both powers, if applicable).
    • Exactly one player meets both of these requirements.
  • Double Win: 18x2 & 12x2
    • Two players win at same time. It's not counted as a draw.
    • 18x2: Both players each have 18+ SCs.
    • 12x2: One player has 12+ SCs in NA. Other player has 12+ SCs in EU.
    • Both players meet both requirements.
    • Players don't have to have the same SC counts; they both win even if one player has a higher count.
  • Draw
    • Normal house rules or DIAS.
    • For the Tournament Through Time, please review the rules for Draws and Scoring.
Building
Max 2 builds per year per power (up to 4 builds per player).
Each of your two powers has its own unit count.
Each can only build in eligible vacant SCs that it controls.
Your two powers can capture each other's SCs.

See the Building Eligibility Charts below for a quick summary of the special cases below.

Major Harbors
Eligible build SC for anybody who captures it.
Only way for Austria & Rhine to build fleets.
  • Venice (Ven)
  • Naples (Nap)
  • Koenigsberg (Kon)
  • New Orleans (NOl)
Cherokee & Shawnee
They can't build fleets, even in Major Harbors.
Any SC in North America is an eligible build location (like Build Anywhere variant).

France & Rhine
Warsaw is an eligible build SC for either France or Rhine.
Montreal is an eligible build SC for France.

Republicans & Federalists
The USA powers treat each other’s home SCs as eligible build SCs.
Savannah is also an eligible build SC for either USA power.

Britain & Canada
Toronto is an eligible build SC for either Britain or Canada.

New Spain
New Spain treats Cádiz as a third home center but is still considered an NA power.
Madrid is also an eligible build SC for New Spain.
New Spain treats Cádiz as a third home center even though it is a North American power. Stylized borders around Cádiz that make it appear to be partially neutral at game start are purely aesthetic; New Spain controls the entire province.

Russia or Denmark-Norway
Stockholm is an eligible build SC for either Russia or Denmark-Norway.

Special Rule: Convoying Between Continents
There is a limit on convoying NA > EU and EU > NA.
An army can only convoy to a non-home continent if going to own controlled SC or adjacent province.
The SC has to be controlled by the same power as the convoying Army (Canadian Army can't use British SC).
No restriction on convoys "going home" back to original continent. No restriction on convoys where the origin and destination are in the same continent.

Water and Terrain
Split Coastlines
  • St. Petersburg (StP nc/sc)
  • Madrid (Mad nc/ec)
  • Rupert's Land (Rup nc/sc)
  • Yorkshire (Ysh ec/wc)
Canals
Just like Denmark or Constantinople in vanilla Diplomacy. There is no canal through Amsterdam or Mecklenburg (i.e. no Kiel canal).
  • Stockholm (Stk)
  • Copenhagen (Cop)
  • Montreal (Mon)
  • Toronto (Tor)
  • Milwaukie (Mwk)
  • Michigan Territory (Mic)
  • Adirondacks (Adi)
  • Niagara (Nia)
Hybrid Provinces
Provinces containing both land and a body or water (like Gibraltar in 1900). Both armies and fleets can pass through. Like canals, but fleets can convoy through.
  • Newfoundland (Nfl)
  • Bahamas (Bah)
  • Hispaniola (His)
  • Dublin (Dub)
  • Cádiz (Cad)
Note that Cádiz is a peninsula. Its adjacency to Madrid is inland. Only armies can pass directly between Madrid & Cádiz, and a fleet in Cádiz may not directly convoy an army to Madrid.

The Great Lakes
The Great lakes are not adjacent to each other. Traveling between them requires passing first through an adjacent canal province.
In prior versions of this variant, the Great Lakes were Hybrid provinces. They are now just water.

List of Locations & Abbreviations
Supply centers are marked with an asterisk. Non-water provinces also indicate their continent (theatre).

Map Clarifications

The island of Sicily is part of the space designated as Naples (Nap). Therefore, Naples is adjacent to the Western Mediterranean (Wes). Nonetheless, the Tyrrhenian Sea (TyS) is still adjacent to the Ionian Sea (Ion) via the inlet between Naples & Sicily.
