The Clan Line was one of Britain’s most distinctive and influential shipping companies, leaving a lasting mark on maritime and economic history. Founded in Glasgow in 1877 by Charles Cayzer, the line quickly grew into a vast fleet that connected Scotland with Africa, India, and beyond. Famed for its combination of commercial power and cultural identity, every ship bore a “Clan” name, giving the company a strong Scottish character that set it apart in the crowded world of British shipping.

The Clan Line played a crucial role in Britain’s growing imperial trade. Its ships carried goods such as jute, tea, and cotton, linking colonial economies to British markets. During both World Wars, the company’s vessels were vital to the Allied cause, transporting troops, supplies, and munitions—often at great risk from enemy submarines. Many were lost, but the service of its crews contributed directly to victory.

Beyond trade and war, the line symbolised the globalisation of the late 19th and early 20th centuries. It represented Scotland’s industrial and maritime strength, while also reflecting the dangers and opportunities of long-distance shipping. Today, the Clan Line stands as a reminder of how shipping shaped commerce, conflict, and community.

To find out more Dr Sam Willis spoke with Jamie Cayzer-Colvin, direct descendent of Charles Cayzer who founded the company, and Susan Scott, the Cayzer family’s archivist who dug out some fabulous items to bring this great story to life.

This episode forms part of a new strand of our podcast: Seapower Past and Present which explores seapower as it is understood and practised in the modern world whilst offering a historical perspective on the themes we explore. Each episode is chosen according to a theme or a location – a hotspot in the modern world where seapower has a major influence on geopolitics. So if you enjoy this episode do please seek out others in this strand – you will shortly be able to find episodes on economic warfare, critical national infrastructure, how technology is changing the nature of warfare at sea; and on hugely significant locations in the modern maritime world – the Black Sea, South China Sea, Middle East and Arctic.

To make this series come alive we’ve teamed up with the Royal Navy Strategic Studies Centre. In each episode you will hear from at least one historian and from at least one practitioner, a member of the armed forces who has direct first hand, personal experience of the topic being discussed.

In this episode, Dr Sam Willis speaks to three guests at the Royal Naval Base in Portsmouth to help us understand seapower in the South China Sea. This region is rich in maritime history and diverse in its modern strategic concerns. To discuss this further, the podcast is joined by Dr Jennifer Sabourah-Till from Permanent Joint Headquarters, who commands joint and multinational military operations on behalf of the Ministry of Defence. Dr Matthew Heaslip, Senior Lecturer in Naval History at the University of Portsmouth, also joins to discuss the Royal Navy in the nineteenth and twentieth centuries. He provides expert knowledge on the use of gunboat diplomacy, amphibious operations and imperial policing in the South China Sea. Also joining Sam in this episode is Joe Reilly, a junior Warfare Officer in the Royal Navy who has previously spent time in the Asia-Pacific theatre on board the patrol vessel HMS Spey. Joe is also a Richmond Fellow with the Royal Navy Strategic Studies Centre.

This episode explores how seapower has been exercised in the Black Sea.

To find out more Dr Sam Willis spoke with Basil Germond, Professor of International Security in the Department of Politics, Philosophy and Religion and Co-Director of the University research institute Security Lancaster. Commander Caroline Tucket provides a fascinating legal perspective on seapower in the Black Sea, in particular looking at the imposition of sanctions and the legal status of the wreck of the Russian warship Moskva, sunk in 2022. A serving naval officer, Caroline is also a member of Navy Legal. To provide an historical perspective Professor Andrew Lambert explores the history of naval operations in the Black Sea during the Crimean War (1835-6). Andrew Lambert is Laughton Professor of Naval History in the Department of War Studies at King's College, London.

This episode explores the relationship between technology and sea power. In an age in which we read in the news about unmanned drones attacking warships at sea and the threat of hypersonic missiles it is particular important that we get to grips with the changes that are happening in our modern world and the historical pathway that has got us to this point.

To find out more Dr Sam Willis spoke with Lieutenant Commander Kit Perry, a serving officer in the Royal Navy who is also studying for a PhD at King’s College in London. Kit’s expertise lies in how new weapon systems, which are underpinned by different types of technological advancements, will change naval warfare. We also hear from

Andrew Lambert, Laughton Professor of Naval History in the Department of War Studies at King's College and recent recipient of the Hattendorf Prize for Distinguished Original Research in Maritime History. As an example of technology dramatically altering naval warfare Andrew explores the development of precision fire on board HMS Excellent in 1850.
