The 1904–1905 Welsh Revival was the largest Christian revival in Wales during the 20th century. It dramatically chnanged the nation of Wales and inspired others to pray for revival in distant places as America, Asia, and Africa

Evan Roberts allowed these women to sing and to preach. It was unheard of for that to happen in the era where women were only homemakers and had no legal right to vote. However, just this former coal miner turned evangleist preaching in churches was also breaking new ground of in a country that had many, many rules making it very difficult to become a formally ordained Reverend.

Stories that came out of the Welsh Revival include the miners donkeys used to be cussed at and abused had to be retrained to do their jobs when their owners had their lives changed and transformed by the Lord

The miners of Wales were a hardy drinking, cussing, womanizing, gambling bunch. When the Revival happened, the salvations en masse meant this changed. As this photo shows, they were now the most godly bunch around. From being the most dangerous area to live and work to being God fearing, respectful, kind people, it astonished the world. From being overrun with work, law enforcement didn't need officers and judges could skip days because there was no cases being tried.
