The Roman Empire was extremely successful and they were able to maintain, gain and consolidate their power mainly through EFFICIENT TRANSPORTATION. In fact the Romans are considered the inventors of paved roads. The roads were also used to transport messages, officials, and tax revenue between the provinces.

Rome was able to gain its empire in large part by extending some form of citizenship to many of the people it conquered. Military expansion drove economic development, bringing enslaved people and loot back to Rome, which in turn transformed the city of Rome and Roman culture.

Invasions by Barbarian tribes The most straightforward theory for Western Rome’s collapse pins the fall on a string of military losses sustained against outside forces. Rome had tangled with Germanic tribes for centuries, but by the 300s “barbarian” groups like the Goths had encroached beyond the Empire’s borders.

War was the key factor in the Aztecs’ rise to power. The Aztecs built alliances, or partnerships, to build their empire. The Aztecs made the people they conquered pay tribute, or give them cotton, gold, or food. The Aztecs controlled a huge trade network.

Machu Picchu Today A UNESCO World Heritage Site since 1983 and designated one of the New Seven Wonders of the World in 2007, Machu Picchu is Peru’s most visited attraction and South America’s most famous ruins, welcoming hundreds of thousands of people a year.

And yet, my response: It’s absolutely worth it, provided you’re prepared to do a bit of planning. Below, I’ve outlined how to make your visit to Machu Picchu a day trip from Cuzco. It requires a little extra forethought, but you can do it, unrushed, in a day — saving you both time and money.

The easiest way to get from Cusco to Machu Picchu is to take the train to Aguas Calientes. It’s a scenic 3.5-hour trip each way along tracks that run right along the Urubamba River in the Sacred Valley, with dramatic canyon walls on either side.
