The Emz Ukaz (eng: The Ems secret decree) is a 
Russian decision. It simulates the banning of writing in Ukrainian language
It is visible if:
- Russia is an Absolute Monarchy
- It owns Kiev
- It has researched phenomenalism
Germany exists and owns Mainz
The decision can be taken once Russia have researched biologism. It gives all Ukrainian pops 3 militancy and removes 2 consciousness.
It is generally not a good decision to take, as it can spark 
Ukraine nationalist rebels.
