Who & why: from around the 2nd century CE, Indian Ocean trade brings Hindu and Buddhist religious practice to small port kingdoms on the northern Malay peninsula, most notably Kedah Tua (centered on the Bujang Valley, where temple ruins and inscriptions survive) and Langkasuka on the east coast, both known to Indian, Chinese, and Arab records under various transliterated names over the centuries. From around the 7th century these kingdoms fall within the tributary orbit of the Sumatra-based Srivijaya empire, and later that of Java's Majapahit, before Kedah's court legendarily converts to Islam in 1136 under Phra Ong Mahawangsa — setting the peninsula's later Malay-Islamic sultanate tradition in motion well before Parameswara founds Malacca around 1400.
What it represents: no flag or banner survives from Kedah Tua, Langkasuka, or any other Hindu-Buddhist-era Malay port kingdom; the surviving Bujang Valley temple remains are religious architecture, not a vexillological record. Shown here honestly blank rather than invented.
World context: this span opens within the era of Indian Ocean trade described in the 1st-century Greco-Roman Periplus of the Erythraean Sea, and runs through Srivijaya's maritime heyday alongside the construction of Java's Borobudur (8th–9th century) and Cambodia's earliest temples at Angkor (9th century onward) — contemporaneous Hindu-Buddhist wonders built by the same trading world that reached Kedah's own shores.
