Master of War

Master of War is a new office on the Small Council of the Seven Kingdoms and then the Six Kingdoms created initially by Cersei Lannister during her incumbency as Queen Regent for King Tommen Baratheon."The House of Black and White" The position was created after the assassination of the Hand of the King, Tywin Lannister. During a period of instability, the position was immediately offered to Tywin's brother Kevan, in an attempt for Cersei to manoeuvre control over the Small Council through nepotism. This was mainly due to Cersei's fear that House Tyrell, specifically led by Olenna, Margaery, and Mace Tyrell, would exert considerable influence over Tommen.
Kevan would come to realise that Cersei was making a grab for power and refused to watch her "stack the Small Council with sycophants," and so he declined the offer and left for Casterly Rock.
Over time, the position has appeared to have gained presence by becoming an officially recognised position on the Small Council. Following Daenerys Targaryen's victory in the Battle of King's Landing, she names Grey Worm her Master of War to the celebration of the Unsullied and Dothraki forces. Later, with Grey Worm having left Westeros, the position becomes vacant once again."The Iron Throne"
During the first Small Council meeting of Brandon Stark, the first elected King of the Andals and the First Men, the new king notes that the Small Council currently lacks a Master of War. This shows that the position itself has gained great legitimacy as a true title on the Small Council.

*Grey Worm, under the brief reign of Daenerys Targaryen. After the assassination of the latter at the hands of Jon Snow, he would resign his post by leaving for Naath.

Cersei inventing the office of Master of War is a condensation of a much longer subplot in the A Song of Ice and Fire novels, in which Cersei drastically reorganizes the Small Council. Her takeover of the Small Council and the "stacking" of it with "sycophants" is a running plotline affecting politics within the capital city. The TV version significantly condenses this, though keeping the general thematic points the same.
The Small Council is gutted after the death of Tywin Lannister, the arrest and sentencing of Tyrion, and Varys' disappearance. Only three members remain: Pycelle as Grand Maester, Ser Kevan as Master of Laws, and Mace Tyrell as Master of Ships. After Kevan's refusal to serve as Hand of the King if he's not declared Regent and subsequent departure of the capital, Cersei moves quickly to establish her own power base and avert the growing influence of House Tyrell. Her first move is declare Lord Gyles Rosby has been named Master of Coin, to prevent the appointment of Mace Tyrell's uncle, Garth "the Gross", who had been invited by Tywin himself. In order to rid herself of Lord Mace, who covets the office of Hand of the King, Cersei charges him with capturing Storm's End, one of the last castles that remains loyal to Stannis Baratheon.
Afterward, Cersei appoints Ser Harys Swyft, Kevan's own father-in-law, as the new Hand, Lord Orton Merryweather, a vassal of House Tyrell, as Master of Laws, and Aurane Waters, a bastard of House Velaryon that bent the knee after being captured at the Battle of the Blackwater, as Master of Ships. She appoints Qyburn as the new Master of Whisperers like in the TV series.
Given that these characters were not introduced in the TV series before and the audience wouldn't be familiar with them, Cersei's reshuffling of the Small Council in the TV version is condensed: Cersei isn't bothering to name a new Hand of the King at all, leaving the office vacant while functionally ruling over the council herself. In the novels, Cersei is technically still Tommen's Regent - but in the TV version, Tommen has apparently reached the age of legal majority in Westeros or is considered "of age" because he has married. Thus Cersei is no longer his regent: Kevan specifically says that she is only the Queen Mother, and makes no mention of being a regent. A Queen Mother has no right to sit on the council if not a regent (though a king can in theory invite any advisors he wants onto his council - but Tommen isn't even present). Mace Tyrell is retained, and simply made both Master of Ships and Master of Coin. Qyburn is the new Master of Whisperers, and Pycelle remains Grand Maester (although he can be removed from the Small Council, his title can only be revoked by the Conclave). As Kevan was apparently going to point out, as Lord Commander of the Kingsguard, her brother Jaime is also supposed to be a member of the Small Council, but he has left the capital (though as it turns out, he volunteered to leave, to deal with events outside the city).
Moreover, Cersei starts making up titles at her whim. In an act of petty resentment, she comes to loathe the idea of anyone else calling himself "master" in his title on the Small Council, feeling this means a loss of control. Therefore, she picks new names based on a few titles from the Free Cities: the Master of Coin is renamed the "Lord Treasurer", the Master of Ships is renamed the "Grand Admiral", and the Master of Laws is renamed the "Justiciar". In Fire and Blood, however, it is revealed these titles were already in use during the Targaryen dynasty.
After Cersei is arrested, and Pycelle invites Kevan back to seize power from her as the new regent, the council apparently just switches back to using the original names. Kevan also gives seats on the council to the Tyrells and their bannermen to undo some of the damage to their alliance that Cersei caused (including Mace Tyrell, Randyll Tarly, and Paxter Redwyne).
