Historical person

Masamune is known for a few things that made him stand out from other daimyo of the time. In particular, his famous crescent-moon-bearing helmet

Smallpox was an infectious disease unique to humans, caused by either of two virus variants, Variola major and Variola minor. The disease is also known by the Latin names Variola or Variola vera, which is a derivative of the Latin varius, meaning "spotted", or varus, meaning "pimple"...

 robbed him of sight in his right eye, though it is unclear exactly how he lost the organ entirely. Some sources say he plucked out the eye himself when a senior member of the clan pointed out that an enemy could grab it in a fight. Others say that he had his trusted retainer Katakura Kojūrō
Katakura Kagetsuna
was a Japanese samurai of the Katakura clan during the late Sengoku period. Also known by his court title, Bichū no Kami , or more commonly, as Katakura Kojūrō. Together with Oniniwa Tsunamoto and Date Shigezane, Kagetsuna was known as one of the "Three Great Men of the Date Clan"...

 gouge out the eye for him. Because of his missing eye, his own mother condemned him as unfit to take over as clan leader and began favoring his younger brother as heir.

The Date clan had built alliances with neighboring clans through marriages over previous generations. However, there were many disputes over the lands during the 15th and 16th centuries.
Shortly after Masamune's succession, a Date retainer named Ōuchi Sadatsuna defected to the Ashina clan of the Aizu

 after this.

With the rise of Masamune, formerly amicable relationships were cast aside as he began to attack and conquer all of the surrounding lands, even those of his kin in Mutsu and Dewa Provinces. Shocked by his ruthlessness, a neighboring family, the Hatakeyama, desperately appealed to Date Terumune to rein in his son's military campaigns. Invited to dinner by the Hatakeyama, Terumune said that he was unable to control his son. In an unheard-of act of desperation, the family kidnapped Terumune and attempted to take him back with them. Masamune, who was out hunting, received word of the kidnapping. When he and his men closed in on the kidnappers as they were about to cross a river, Terumune ordered his son's men to kill all the enemy, even at the cost of his own life. Masamune's men did as they were told and killed everyone, including Terumune. Masamune continued the war and tortured and killed the families of his father's kidnappers.

After defeating the Ashina in 1589, he made the Aizu domain his base of operations.

Meanwhile, his relationship with his mother, Yoshihime, continued to deteriorate. Yoshihime insisted Masamune resign the succession to her second son, Kojiro. According to some historians, she tried to poison him one night while serving him dinner. Masamune consequently killed his own brother in order to come to power. After this tragedy, his mother fled to her brother's home, the Mogami clan.

In 1590, Toyotomi Hideyoshi

 daimyos to participate in the campaign. Although Masamune refused Hideyoshi's demands at first, he had no real choice in the matter since Hideyoshi was the virtual ruler of Japan. Masamune still delayed, infuriating Hideyoshi. Expecting to be executed, Masamune, wearing his finest clothes and showing no fear, faced his angry overlord. Not wanting further trouble, Hideyoshi spared his life, saying that "He could be of some use".

After serving Hideyoshi for a time, he was given Iwatesawa castle and the surrounding lands as his home domain. Masamune moved there in 1591, rebuilt the castle, renamed it Iwadeyama
Iwadeyama, Miyagi

, and encouraged the growth of a town at its base. Masamune stayed at Iwadeyama for 13 years and turned the region into a major political and economic center. He and his men served with distinction in the Korean invasions under Hideyoshi and, after Hideyoshi's death, he began to support Tokugawa Ieyasu

Tokugawa Ieyasu awarded Masamune the lordship of the huge and profitable Sendai Domain
Sendai Domain

 domain, but, even after substantial improvements were made, the land only produced 640,000 koku, most of which was used to feed the Edo region. In 1604, Masamune, accompanied by 52,000 vassals and their families, moved to what was then the small fishing village of Sendai

. He left his fourth son, Date Muneyasu, to rule Iwadeyama. Masamune would turn Sendai into a large and prosperous city.

Although Masamune was a patron of the arts and sympathized with foreign causes, he was also an aggressive and ambitious daimyo. When he first took over the Date clan, he suffered a few major defeats from powerful and influential clans such as the Ashina. These defeats were arguably caused by recklessness on Masamune's part.

Being a major power in northern Japan, Masamune was naturally viewed with suspicion, as any potential rival would be viewed. Toyotomi Hideyoshi reduced the size of his land holdings after his tardiness in coming to the Siege of Odawara

. Later in his life, Tokugawa Ieyasu increased the size of his lands again, but was constantly suspicious of Masamune and his policies. He was particularly suspicious of foreign missionaries, whom he perceived as a threat to his power.

Although Tokugawa Ieyasu and other Date allies were always suspicious of him, Date Masamune for the most part served the Tokugawa and Toyotomi loyally. He took part in Hideyoshi's campaigns in Korea, and in the Osaka campaigns

. He built many palaces and worked on many projects to beautify the region. He is also known to have encouraged foreigners to come to his land. It is unlikely that Masamune himself was secretly a Christian convert. Even though he funded and promoted an envoy to establish relations with the Pope in Rome, he was likely motivated at least in part by a desire for foreign technology, similar to that of other lords, such as Oda Nobunaga

 from the hands of Tokugawa Ieyasu. Date Masamune allowed Sotelo as well as other missionaries to practice their religion and win converts in Tōhoku.
