In the post-independence era...

[rainous]

"In the post-independence era riddled with social unrest, ~~."

To make this phrase grammatically correct, do I need to switch "the" to "a"?

Or does it not matter?

If yes, would you please explain why?

Thanks

No. "the" is used to point to a specific era. If you changed to "a", you would change the meaning to one of many eras - It could be any of a number of eras.
