Help Identify Please - Old Stamp [opgelost]

Hello, I'm having troubles identifying this Stamp.
Can someone help me identify it?

I think I'm just pointing out the obvious and scratching the surface here, but here it goes anyway...

It's a stamp depicting Marianne, the symbol of the French Republic and the goddess of liberty.

The text on top reads, directly, "By Force but for Right", meaning "By force but for the law" or "for good". Basically.

At Marianne's feet it says "For human rights - For the nation's rights".

The banner at the bottom says "Committee of Patriotic France - Buenos Aires".

The dates, 1789 and 1915, are a bit of mystery to me. The French Revolution began in 1789 and it's still a very significant date in France, but I'm having trouble linking it specifically to 1915. The best I can come up with is it was maybe a means of stirring up some patriotism and potentially recruitment for WWI. There's a fairly strong French presence in Buenos Aires.

I also found two more:

I welcome anyone correcting me on any of this. Particularly the translations, my French is good enough for my own reading and comprehension but if you want a nuanced translation I may not be your best source.

Sorry I don't have a better answer for you, hopefully someone else here will.

MonaSeaclaid said it all, perfect translations and description! 1789-1915 are probably just date of the first Revolution, and the date it was issued

Seriously, that is one gorgeous stamp.

Thank you CassTaylor! Yeah it really is nice, isn't it?
