Before tens of thousands of soldiers and civilians marched before him, along with some of the most fearsome weapons at his command, North Korean leader Kim Jong-Un and his audience were shown portraits of his grandfather and father.
Pyongyang's giant weekend parade was intended as a show of military strength aimed at Washington, Seoul, Tokyo and others with tensions soaring over its nuclear and missile ambitions.
It was also a domestic affirmation of Kim family authority over the country, analysts say.
Banners hung from buildings around Kim Il-Sung Square, which is named for the founder of the Democratic People's Republic of Korea -- as the North is officially known -- and its ruling dynasty.
One offered Kim Il-Sung "eternal glory", with another reading: "Let us safeguard with our lives the central committee of the party headed by the great comrade Kim Jong- Un."
Despite dying in 1994, Kim Il-Sung remains the titular leader of the North, where he is "Eternal President", and his "Juche" or "self-reliance" philosophy - centred on the concept that "man is the master of all things" - is proclaimed as its guiding tenet.
In a speech ahead of the march, senior Kim aide Choe Ryong-Hae declared it "a loyal report to the great president Kim Il-Sung and (his son and successor) the great leader Kim Jong-Il that we are maintaining the revolutionary cause".
Pictures of the two men are ubiquitous throughout the country, where Supreme Leader Kim Jong-Un -- still only in his 30s -- is consistently referred to as the "respected general".
The parade was "a big deal for the Kim family cult in the North", said senior Rand Organisation researcher Bruce Bennett.
At the same time, Pyongyang was "sending messages of deterrence toward everyone", he added.
The new US administration of Donald Trump has ramped up pressure on Pyongyang and declared that Washington's "strategic patience" is over.
The North, which says it needs nuclear weapons to protect itself against the threat of invasion, failed with a missile launch the day after the procession and its exact military capabilities are shrouded in secrecy.
But it invites international media to observe the parades, and analysts scurry to examine pictures of the missiles on display -- whether real or mock-ups -- for clues about its progress.
Choe told his audiences in the square, the country and abroad that the North was a "powerful nuclear-armed state" and "Asia's leader in rocketry".
North Korean parades are a regular occurrence, said Jeffrey Lewis, of the Middlebury Institute of International Studies in California. "It's like Christmas, but for Juche instead of Jesus."
Religious terminology is prominent at Kim Il-Sung's birthplace, a heavily restored grave-keeper's cottage at Mangyongdae, a rural idyll overlooking islands in the stream of the Taedong river outside the capital.
"This is the sacred place that all the people of the world look up to," said guide Chon Hyon-Ran, who referred to April 15 as Kim's "birthdaymas".
"Relics" of family life are on display, from Kim's great-grandfather's pipe to an inkstone used by the future president.
