Aztec Technology
The Aztec didn't have the technology we have today, but in ways it was just as amazing. Some of their weapons were made out of obsidian (almost the strongest block in Minecraft). They used the wheel on some of their toys, and if they hadn't been conquered, they probably would have developed a cart. Around the time that they were overthrown by the Spanish, they were experimenting with copper. They even made a couple of copper axes. They also had small drills made out of reed. This shows how genius these people were.
