The idea of Masonic brotherhood probably descends from a 16th-century legal definition of a brother as one who has taken an oath of mutual support to another. Accordingly, Masons swear at each degree to keep the contents of that degree secret, and to support and protect their brethren unless they have broken the law. In most Lodges the oath or obligation is taken on a Volume of Sacred Law, whichever book of divine revelation is appropriate to the religious beliefs of the individual brother (usually the Bible in the Anglo-American tradition). In Progressive continental Freemasonry, books other than scripture are permissible, a cause of rupture between Grand Lodges.
Mason swear at each degree to do what?

With the redevelopment of Las Vegas and the opening of two casinos in Connecticut in the early 1990s, along with newly built casinos in the nearby Philadelphia metro area in the 2000s, Atlantic City's tourism began to decline due to its failure to diversify away from gaming. Determined to expand, in 1999 the Atlantic City Redevelopment Authority partnered with Las Vegas casino mogul Steve Wynn to develop a new roadway to a barren section of the city near the Marina. Nicknamed "The Tunnel Project", Steve Wynn planned the proposed 'Mirage Atlantic City' around the idea that he would connect the $330 million tunnel stretching 2.5 miles (4.0 km) from the Atlantic City Expressway to his new resort. The roadway was later officially named the Atlantic City-Brigantine Connector, and funnels incoming traffic off of the expressway into the city's marina district and Brigantine, New Jersey.

The winner, Taira no Kiyomori, became an imperial advisor, and was the first warrior to attain such a position. He eventually seized control of the central government, establishing the first samurai-dominated government and relegating the Emperor to figurehead status. However, the Taira clan was still very conservative when compared to its eventual successor, the Minamoto, and instead of expanding or strengthening its military might, the clan had its women marry Emperors and exercise control through the Emperor.
What role did the Emperor have in the samurai-controlled government?
figurehead
