Aztec Civilization The Aztec Empire flourished between c. 1345 and 1521 CE and, at its greatest extent, covered most of northern Mesoamerica. Aztec warriors were able to dominate their neighbouring states and permit rulers such as Motecuhzoma II to impose Aztec ideals and religion across Mexico. Highly accomplished in agriculture and trade, the last of the great Mesoamerican civilizations was also noted for its art and architecture which ranks amongst the finest ever produced on the continent. The Aztec state is actually the most well documented Mesoamerican civilization with sources including archaeology, native books (codices) and lengthy and detailed accounts from their Spanish conquerors - both by military men and Christian clergy. Historical Overview
Tarlton Law Library - Aztec and Maya Law - online exhibit The Aztec empire was made up of a series of city-states known as altepetl. Each altepetl was ruled by a supreme leader (tlatoani) and a supreme judge and administrator (cihuacoatl). The tlatoani of the capital city of Tenochtitlan served as the Emperor (Huey Tlatoani) of the Aztec empire. The tlatoani was the ultimate owner of all land in his city-state, received tribute, oversaw markets and temples, led the military, and resolved judicial disputes.

15 Effective Tools for Visual Knowledge Management Since I started my quest a few years ago searching for the ultimate knowledge management tool, I’ve discovered a number of interesting applications that help people efficiently organize information. There certainly is no shortage of solutions for this problem domain. Many tools exist that offer the ability to discover, save, organize, search, and retrieve information. However, I’ve noticed a trend in recent years, and some newer applications are focusing more on the visual representation and relationship of knowledge. I believe this is in part due to the wider adoption of mind mapping (and concept mapping), and leveraging concepts and advances in the semantic web community. Intelligent Life magazine In 1914 John G. Bartholomew, the scion of an Edinburgh mapmaking family and cartographer royal to King George V, published “An Atlas of Economic Geography”. It was a book intended for schoolboys and contained everything a thrusting young entrepreneur, imperialist, trader or traveller could need. As well as the predictable charts of rainfall, temperature and topography, it had maps showing where you could find rubber, cotton or rice; maps showing the distribution of commercial languages, so that if you wanted to do business in Indonesia you knew to do so in Dutch; and maps showing the spread of climatic diseases, so that if you did find yourself in Indonesia you knew to look out for tropical dysentery. It also contained the map you see here, which told you how long it would take to get there from London: between 20 and 30 days. This is an isochronic map – isochrones being lines joining points accessible in the same amount of time – and it tells a story about how travel was changing.
The 15 best tools for data visualisation It's often said that data is the new world currency, and the web is the exchange bureau through which it's traded. As consumers, we're positively swimming in data; it's everywhere from labels on food packaging design to World Health Organisation reports. As a result, for the designer it's becoming increasingly difficult to present data in a way that stands out from the mass of competing data streams. One of the best ways to get your message across is to use a visualization to quickly draw attention to the key messages, and by presenting data visually it's also possible to uncover surprising patterns and observations that wouldn't be apparent from looking at stats alone. And nowadays, there's plenty of free graphic design software to help you do just that.
