Explanation: Cato the Elder was a politician in Mid-Republic era Rome, most active in the Second and Third Punic Wars.
He was an insane conservative who even Roman authors (themselves tending towards conservatism and misogyny) noted with discomfort that he treated the women in his family little better than he treated his slaves - and he treated his slaves poorly by the standards of aristocratic Romans. Not a pleasant fellow. He was well-connected with the aristocracy, but not particularly popular with the Roman people.
He spent an inordinate amount of time attempting to police public morality. He attempted to indefinitely prolong a ban on women wearing jewelry in public that was implemented during the Second Punic War as an attempt to induce people to sell their valuables for The War Effort(tm). He wanted to prolong it not for fiscal reasons, but openly and explicitly because he thought women shouldn't be allowed such incredible power as [checks notes] owning valuable objects and choosing what they wear. This lunacy was defeated by vote of the popular assemblies.
His career reads like a long list of shit like that. He was a major opponent of the Roman general Scipio Africanus (who was very popular with the people) who saved the Republic during the Second Punic War, taking every opportunity to harass and defame him until Africanus retired from politics at an early age and declared (due to his mistreatment by conservatives in the Senate) "Ungrateful fatherland, you will not even have my bones!" and was buried outside of Rome.
Cato considered such notions as Greek 'philosophy' and 'literature' and 'medicine' to be dangerous ideas in need of suppressing. He believed that Greek doctors were all part of a conspiracy to kill foreigners (like Romans), and only charged money for it to escape suspicion. He was a notorious ascetic who insisted that only his way of life was valid, and ate large amounts of cabbage, regarding it as a cure for most illnesses.
He believed the youth were becoming degenerate and degraded compared to the youth of HIS day, and needed more war and hardship to toughen them up. For reference, the youth of his generation was so 'honorable' that a group of Cato's fellow aristocratic youths had to be threatened at swordpoint by Scipio Africanus to stop them from fleeing the Republic during the Second Punic War, when the Republic was threatened with total destruction if its citizens did not serve to resist a foreign invader, and numerous sons of Senators and rich men were stripped of their citizenship during his youth for dodging the draft while poorer men did their duty. What a mighty generation.
He's mostly remembered in the modern day for ending every speech, no matter the topic, in the Senate with "And furthermore, I believe Carthage must be destroyed (Carthago Delenda Est)", in an attempt to exterminate the then-powerless city-state of Carthage after it had been reduced to a tributary state of Rome.
It's catchy, but the context of it, like most of Cato's life, is shitty.
He would have an equally-famous descendent known as Cato the Younger, who was also an ultraconservative shithead.
