Such a time - Tradução em português

Hi everyone, I'd like to know the translation for this: "such a time"
It's from an article I'm reading.
This is the part of the sentence that I need help:

He says every 50 years or so the country experiences a period of extreme partisanship. He says the late 1700s were such a time. That partisanship helped split the Federalist Party.

thanks in advance
