This graphic by HMY Yachts looks at which vessels held the title of the world’s largest passenger ship over time, and how these vessels have evolved since the early 19th century.

Different Types of Passenger Ships

Before diving into the ranking, it’s worth explaining what constitutes a passenger ship. Passenger ships are vessels whose main purpose is to transport people rather than goods. In modern times, there are three types of passenger ships:

Cruise ships: Used for vacationing, with a priority on amenities and luxury Ferries: Typically used for shorter day trips, or overnight transport Ocean liners: The traditional mode of maritime transport, with a priority on speed

Traditional ocean liners are becoming obsolete, largely because of advancements in other modes of transportation such as rail, automobile, and air travel. In other words, the main priority for passenger ships has changed over the years, shifting from transportation to recreation. Now, luxury is the central focus, meaning extravagance is part of the whole cruise ship experience. For example, the Navigator of the Seas (which was the largest passenger ship from 2002-2003) has $8.5 million worth of artwork displayed throughout the ship.

A Full Breakdown: Biggest Passenger Ships By Tonnage

Now that we’ve touched on the definition of a passenger ship and how they’ve evolved over the years, let’s take a look at some of the largest passenger ships in history. The first vessel on the list is the SS Royal William. Built in Eastern Canada in the early 1800s, this ship was originally built for domestic travel within Canada. In addition to being the largest passenger ship of its time, it’s often credited as being the first ship to travel across the Atlantic Ocean almost fully by steam engine. However, some sources claim the Dutch-owned vessel Curaçao completed a steam-powered journey in 1827—six years before the SS Royal William. In 1837, The SS Royal William was dethroned by the SS Great Western, only to change hands dozens of times before 1912, when the Titanic entered the scene. The Titanic was one of three ships in the Olympic-class line. Of the three, two of them sank—the Titanic in 1912, and the HMHS Britannic in 1916, during World War I. Some historians believe these ships sank as a result of their faulty bulkhead design. Fast forward to today, and the Symphony of the Seas is now the world’s largest passenger ship. While it boasts 228,081 in gross tonnage, it uses 25% less fuel than its sister ships (which are slightly smaller).

COVID-19’s Impact on Cruise Ships

2020 was a tough year for the cruise ship industry, as travel restrictions and onboard outbreaks halted the $150 billion industry. As a result, some operations were forced to downsize—for instance, the notable cruise operation Carnival removed 13 ships from its fleet in July 2020. That being said, restrictions are slowly beginning to loosen, and industry experts remain hopeful that things will look different in 2021 as more people begin to come back on board. 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.
