An 1836 Proposal for the union of Norway and Sweden
I saw this in Twitter from this account with the description and thought it was pretty cool.
The 1836 proposal for a Sweden–Norway union flag was an early attempt to create a shared national symbol while preserving the identities of both kingdoms. It was never officially adopted.
After the Napoleonic Wars, Norway entered a personal union with Sweden under a shared monarch while retaining its own constitution, parliament, and most domestic institutions.
One proposed union flag combined symbols linked to both kingdoms in a swallow-tailed military-style design rather than merging the familiar Nordic crosses. It was never adopted. In 1844, King Oscar I instead introduced separate national flags featuring a shared union badge in the canton, a system that remained until the union ended peacefully in 1905.
