Nation building rip

I formed my own nation
Once in my backyard
I surveyed its boundaries
In the ages since kiyard
I established my structure
Freestanding and pristine
I founded a capital city
And harvested mint tea
Hey - I've got myself a country
Hey - with a constitution defined
Nation building provincial planning
The UPR's short life spanning
The UDAST's short life spanning
I was not the only one
Who built themselves sovereignty
I have this friend who
Discovered the UDAST
His landscape was vast and all
And was formed on a farm
It advanced in technology
But was no cause for alarm
