I don’t really know what kind of history books bigots like you read.
The Great Libraries of Timbuktu? The steel metallurgy of the Haya? Dentistry? Caesarean section? Premature neonatal care? Mathematics, architecture, engineering?
I know it’s hard for a racist like you who imagines “technological advancement” to be some kind of end-all-be-all, or proof of some “inherent intelligence”. I know, I know. It’s hard to imagine, but Europeans have been drawing knowledge from everyone around them since the dawn of time. What did you think ended the Dark Ages?
Your magical (read: white supremacist) idea of a purely 'white' Rome never existed.
The Minoan culture on the island of Crete between 1500-1700 B.C.E. had a highly developed waste management system. They had very advanced plumbing and designed places to dispose of organic wastes. Knossos, the capital city, had a central courtyard with baths that were filled and emptied using terra-cotta pipes. This piping system is similar to techniques used today. They had large sewers built of stone.”
In case you needed further clarification, neither the Minoans nor other (later) Greeks were ethnically uniform. They also had the first flush toilets, dating back to 18th century B.C.E. They had flushing toilets, with wooden seats and an overhead reservoir. The Minoan royals were the last group to use flushing toilets until the re-development of that technology in 1596.
Oh, and look the Mayans had indoor plumbing, acqueducts, and pressurized water too. I mean, you can ignore that the area Mayans lived in had little to few rivers, no lakes or standing water, nor other sources of running water, while simultaneously dealing with monsoons and flooding due to one of the heaviest yearly rainfalls in the Americas.
Classic Maya even used household water filters using locally abundant limestone carved into a porous cylinder, made so as to work in a manner strikingly similar to modern ceramic water filters.
Of course, by this time millenia later none of your precious “white people” had developed any methods besides shitting in pots.
All houses in the major cities of Harappa and Mohenjo−daro had access to water and drainage facilities. Waste water was directed to covered drains which lined the major streets directed to covered drains, which lined the major streets. Each home had its own private drinking well and its own private bathroom. The mains that carried wastewater to a cesspit were tall enough for people to walk through. Reservoirs, a central drainage system, fresh water pumped into the homes. Pools. Baths.
Filters for solid waste.
Sorry, what were the British doing up until like, 200 years ago? Shitting in the streets? Oh yeah.
I mean, I could get into how by the Shang Dynasty (roughly 1600 B.C.E.), China had sophisticated plumbing including pressure inverted siphons.
Or into the city of Amarna, Ancient Egypt. Or Persepolis, Persia and the Achaemenids in 600 B.C.E.
But, I mean, it sounds like the only one still in the Bronze Age is you.
I love it when people bring facts to white supremacist logic.
