Treaty of London (1864) is a decision available to 
United Kingdom relating the fate of the 
Ionian Islands. It is not to be confused with Treaty of London a decision available to the 
Netherlands. Unlike the similar decisions like Seward's Icebox (annexing 
Hawaii) and End the Merina Monarchy (annexing 
Madagascar), it can be taken if Ionian Islands are controlled by a player, and is therefore a significantly bigger risk to a player controlled Ionian Islands.

Effects
- Greece inherits Ionian Islands
- +50 relations with Greece
- +50 influence with Greece

It is a good decision to take as long as one have above 4 infamy, as Ionian Islands are not worth a lot compared to what can be taken for the infamy. At the 1861 starting date, it can be taken from day one.
Ingame description
The Ionian Islands had been an amicable protectorate of The United Kingdom ever since the end of the Napoelonic Wars. In 1862 the protectorate was deemed too expensive to maintain, and the islands were, after two years negotiations, ceded to Greece.
