Do you know who invented barbed wire?

One of the articles about the invention of barbed wire reads: "In 1867, Joseph worked on a ranch in California and often read books while herding sheep. When he was immersed in reading, the livestock often knocked down the grazing fence made of wooden stakes and barbed wire and ran to the nearby fields to steal crops.

The rancher was very angry about this and threatened to fire him. Joseph observed that sheep rarely crossed the rose fence covered with thorns. So, a lazy idea came to his mind: why not use thin wire to make a barbed net? He cut the thin wire into small pieces and wrapped it around the wire fence, and cut the end of the wire into sharp thorns.

Now, the sheep who want to steal crops can only "look at the net and sigh", and Joseph no longer has to worry about being fired..." Why am I interested in barbed wire? Because in recent years, I often walk in the border areas of China (this kind of walking requires permission from the border guards), and I found that a landscape that has never been seen before has appeared on the border: along the border line, barbed wire fences are built not far from the border and often stretch for thousands of kilometers - barbed wire fences are built near the China-North Korea border, and also near the borders of China, Russia, Mongolia, Kazakhstan, Kyrgyzstan, Tajikistan and other countries.

Think about it, the border between China and Mongolia is about 4,710 kilometers long, the border between China and Russia is about 4,300 kilometers long, and the border between China and Kazakhstan is about 1,700 kilometers long... The barbed wires near these borders are connected together, and they are more than 10,000 miles long. What kind of landscape is this?

Joseph probably never dreamed that his little invention would create such a grand landscape, nor did he expect that the barbed wire he originally used to restrict sheep would soon be used to restrict people: barbed wire (hereinafter referred to as "barbed wire") is not only used to encircle people in prisons, concentration camps, and prisoner-of-war camps, but also widely used on the battlefield.

Some people list this barbed wire as "one of the seven patents that changed the face of the world" because the innovation of this technology has brought about institutional innovation. Some economists say that barbed wire gave birth to the establishment of the early property rights system in the western United States (barbed wire fences helped ranches determine boundaries and thus promoted economic and social development), which is the greatest contribution of barbed wire.
