Why the Hanseatic League has no territory on this map

The decision

There is no Hanseatic territory layer on this atlas, and there will not be one. The League is drawn as cities, corridors and events, and never as a shaded area.

Why

The Hanse was an association of towns, not a state. It had no capital, no sovereign, no standing army and no border. What it had were privileges in places: the right to trade on particular terms in Bruges, London, Bergen and Novgorod, and agreements among member cities to act together in defending those terms.

None of that has an edge. A merchant travelling between two Hanseatic cities passed through territory belonging to counts, bishops, kings and the Empire, none of it Hanseatic in any sense. The League’s power over that road was the power to withdraw from it.

Shading the space between the cities would draw exactly the thing that did not exist. And it would draw it convincingly, because a polygon on a modern map reads as sovereignty whatever the caption says.

What we draw instead

Places, with an explicit participation class - a leading city, an active city, a city merely represented at a Hansetag, a Kontor, a foreign branch, an associated town, a market. These are institutional relationships, and they changed. A city that attended one diet and never returned is not the same as Lübeck.

Corridors, with an evidence type saying how well attested each one is - a documented route, a repeatedly evidenced commercial connection, or a generalised reconstruction. Line width carries that distinction, so the strength of the evidence is visible on the map rather than buried in a field.

Events - privileges granted, confirmed and restricted, embargoes, conflicts, peace treaties, Hansetage, Kontor relocations and closures. The League’s history is a history of institutional acts at named places, and that is how it is drawn.

What this costs

Honesty here costs legibility. A territorial blob would be easier to grasp at a glance and would sit more comfortably beside the Roman and Venetian layers, which do have extents.

The comparison is the point. Venice ran a maritime empire with governors and subject cities, and it gets fills - carefully hedged ones. The Hanse ran a network of privileges, and it gets nodes and edges. Two different kinds of power should not look the same on a map.

Where this came from

This is an editorial and historiographical decision, not a technical one, which is why it is published here rather than left in the repository’s decisions log. That log also records the engineering decisions behind the same layers - file formats, compile contracts, identifier schemes - and those are not historical arguments and are not published as though they were.
