LYNDA N. SHAFFER : MARITIME SOUTHEAST ASIA TO 1500

In this book — "Maritime Southeast Asia to 1500" (1996), part of the Sources and Studies in World History series — Lynda Norene Shaffer makes the Malay seafarer central to early world history.

Her main argument about them is:

1. They mastered the monsoon very early.

"from 300 B.C., by which time their inhabitants had learned to sail the monsoon winds, to A.D. 1528"

Shaffer defines her region as the Malay Peninsula, the Vietnamese coast, and present-day Indonesia and the Philippines and argues it was already part of inter-regional trade by the 1st millennium B.C.E.

2. They invented key maritime technologies that the world later adopted.

The review of the book summarises her opening point:

"Taking a roughly chronological approach, Shaffer begins by pointing out some of the early contributions of Malay sailors to naval technologies, such as the balancelug sail and the design of the jong (from which the English word 'junk' is derived)."

In later chapters and in other scholars citing her, this is expanded to:

• The outrigger — to stabilise vessels in the open ocean
• The balance-lug sail — an oblique, four-sail rig that could take wind from behind and spill it from one sail to another, allowing sailing in strong winds without high masts
• The jong / Kunlun bo — the large sewn-plank ship Chinese sources call Kunlun bo. 50-60+ metres long, multiple layers of planks, no iron nails, carrying 600-1000 people + 600 tonnes of cargo

3. They were expert navigators without instruments.

As summarised by scholars using Shaffer:

"The then Malay mariners were skilful sailors, voyaging through the open seas for thousands of miles without the help of written charts and compasses."

And she notes Chinese records from BCE:

"BCE describes the Malays as expert sailors who approached the Chinese shores... as 'celestial navigation', as referenced by Shaffer in his book, Maritime Southeast Asia to 1500 (1996, 12)."

For Shaffer this is the foundation of her larger thesis — later called "Southernisation": it was Malay/Indonesian sailors from Srivijaya, Funan, and later Melaka who connected India, China, the Middle East and the Mediterranean, making Southeast Asia not a peripheral receiver but a creator and driver of the early maritime Silk Road. The Malay port-polities like Jambi, Palembang (Srivijaya), Melaka, Pattani, and Johor-Riau were city-port kingdoms because of this seafaring skill.

It's from her famous article "Southernisation" (Journal of World History, 1994), which she later expanded in "Maritime Southeast Asia to 1500":

"Malay sailors had reached the eastern coast of Africa at least by the 1st century BCE, if not earlier."

What she means by it:

1. Not just coast-hugging, but open-ocean monsoon sailing.

Shaffer argues that by the last centuries BCE, Malay-Polynesian sailors had learned to ride the monsoon system in both directions. The regular wind patterns allowed "fairly easy and consistent travel" across the Indian Ocean.

2. Evidence she cites:

• Crops: They brought Southeast Asian crops, "such as bananas and coconuts as far as East Africa" — bananas are not native to Africa and had to be introduced by Austronesians.
• The Settlement of Madagascar: "Perhaps the most stunning evidence of their skill is that Malay-Polynesian peoples reached and settled the island of Madagascar (off the coast of East Africa) around this era—a distance of over 4,000 miles across open ocean."
• Classical sources: The "Periplus of the Erythraean Sea" (1st century CE) and Ptolemy describe people from beyond India in East African waters, which Shaffer identifies as Kunlun / Malay sailors.

In her framework, this is the start of "Southernisation" — the process that made the "Southern Ocean" — her term for all waters from the South China Sea to the eastern coast of Africa — a single integrated zone of exchange, centuries before European "globalisation".

What modern archaeology says now:

Most archaeologists today put the permanent settlement of Madagascar a bit later, around 400-500 CE, based on language and DNA, though trans-Indian Ocean contacts — especially plant transfers like banana, taro, and the outrigger canoe technology itself — could have begun in the last centuries BCE, just as Shaffer argued.

Shaffer — she was arguing that Austronesian Malays were in East Africa by the 1st century BCE at the latest, making them the first true trans-oceanic sailors in world history.
