It would be no small task, and simply weighing the relative importance of so many great people, technological achievements, and pivotal events would be a tiny miracle in itself. While that seems like a challenge, imagine going a few steps further. Instead of a timeline for just one country, what about creating a graphical timeline showing the history of the entire world over a 4,000 year time period, all while having no access to computers or the internet?

An All-Encompassing Timeline?

Today’s infographic, created all the way back in 1931 by a man named John B. Sparks, maps the ebb and flow of global power going all the way back to 2,000 B.C. on one coherent timeline. View a high resolution version of this graphic Histomap, published by Rand McNally in 1931, is an ambitious attempt at fitting a mountain of historical information onto a five-foot-long poster. The poster cost $1 at the time, which would equal approximately $18 when accounting for inflation. Although the distribution of power is not quantitatively defined on the x-axis, it does provide a rare example of looking at historic civilizations in relative terms. While the Roman Empire takes up a lot of real estate during its Golden Age, for example, we still get a decent look at what was happening in other parts of the world during that period. The visualization is also effective at showing the ascent and decline of various competing states, nations, and empires. Did Sparks see world history as a zero-sum exercise; a collection of nations battling one another for control over scarce territory and resources?

Timeline Caveats

Crowning a world leader at certain points in history is relatively easy, but divvying up influence or power to everyone across 4,000 years requires some creativity, and likely some guesswork, as well. Some would argue that the lack of hard data makes it impossible to draw these types of conclusions (though there have been other more quantitative approaches.) Another obvious criticism is that the measures of influence are skewed in favor of Western powers. China’s “seam”, for example, is suspiciously thin throughout the length of the timeline. Certainly, the creator’s biases and blind spots become more apparent in the information-abundant 21st century. Lastly, Histomap refers to various cultural and racial groups using terms that may seem rather dated to today’s viewers.

The Legacy of Histomap

John Spark’s creation is an admirable attempt at making history more approachable and entertaining. Today, we have seemingly limitless access to information, but in the 1930s an all encompassing timeline of history would have been incredibly useful and groundbreaking. Indeed, the map’s publisher characterized the piece as a useful tool for examining the correlation between different empires during points in history.

Critiques aside, work like this paved the way for the production of modern data visualizations and charts that help people better understand the world around them today. This post was first published in 2017. We have since updated it, adding in new content for 2021. on Even while political regimes across these countries have changed over time, they’ve largely followed a few different types of governance. Today, every country can ultimately be classified into just nine broad forms of government systems. This map by Truman Du uses information from Wikipedia to map the government systems that rule the world today.

Countries By Type of Government

It’s important to note that this map charts government systems according to each country’s legal framework. Many countries have constitutions stating their de jure or legally recognized system of government, but their de facto or realized form of governance may be quite different. Here is a list of the stated government system of UN member states and observers as of January 2023: Let’s take a closer look at some of these systems.

Monarchies

Brought back into the spotlight after the death of Queen Elizabeth II of England in September 2022, this form of government has a single ruler. They carry titles from king and queen to sultan or emperor, and their government systems can be further divided into three modern types: constitutional, semi-constitutional, and absolute. A constitutional monarchy sees the monarch act as head of state within the parameters of a constitution, giving them little to no real power. For example, King Charles III is the head of 15 Commonwealth nations including Canada and Australia. However, each has their own head of government. On the other hand, a semi-constitutional monarchy lets the monarch or ruling royal family retain substantial political powers, as is the case in Jordan and Morocco. However, their monarchs still rule the country according to a democratic constitution and in concert with other institutions. Finally, an absolute monarchy is most like the monarchies of old, where the ruler has full power over governance, with modern examples including Saudi Arabia and Vatican City.

Republics

Unlike monarchies, the people hold the power in a republic government system, directly electing representatives to form government. Again, there are multiple types of modern republic governments: presidential, semi-presidential, and parliamentary. The presidential republic could be considered a direct progression from monarchies. This system has a strong and independent chief executive with extensive powers when it comes to domestic affairs and foreign policy. An example of this is the United States, where the President is both the head of state and the head of government. In a semi-presidential republic, the president is the head of state and has some executive powers that are independent of the legislature. However, the prime minister (or chancellor or equivalent title) is the head of government, responsible to the legislature along with the cabinet. Russia is a classic example of this type of government. The last type of republic system is parliamentary. In this system, the president is a figurehead, while the head of government holds real power and is validated by and accountable to the parliament. This type of system can be seen in Germany, Italy, and India and is akin to constitutional monarchies. It’s also important to point out that some parliamentary republic systems operate slightly differently. For example in South Africa, the president is both the head of state and government, but is elected directly by the legislature. This leaves them (and their ministries) potentially subject to parliamentary confidence.

One-Party State

Many of the systems above involve multiple political parties vying to rule and govern their respective countries. In a one-party state, also called a single-party state or single-party system, only one political party has the right to form government. All other political parties are either outlawed or only allowed limited participation in elections. In this system, a country’s head of state and head of government can be executive or ceremonial but political power is constitutionally linked to a single political movement. China is the most well-known example of this government system, with the General Secretary of the Communist Party of China ruling as the de facto leader since 1989.

Provisional

The final form of government is a provisional government formed as an interim or transitional government. In this system, an emergency governmental body is created to manage political transitions after the collapse of a government, or when a new state is formed. Often these evolve into fully constitutionalized systems, but sometimes they hold power for longer than expected. Some examples of countries that are considered provisional include Libya, Burkina Faso, and Chad.
