query: When was Nova Gorica established and why?
answer: Nova Gorica was formally established as an urban municipality in 1952.  It was built after 1947, following a peace treaty that shifted the border between Yugoslavia and Italy, leaving Gorizia separated from its northern and eastern suburbs.  The new town was created to connect these previously separated, predominantly Slovene-inhabited suburbs into a cohesive urban space.
