After King Solomon's passing in 797 BCE, ten of the twelve tribes of Israel, led by Jeroboam ben Nebat of the tribe of Ephraim, rebelled against Solomon's son and heir, Rehoboam. The Holy Land split into two kingdoms: the "Kingdom of Israel" in the north, with Jeroboam as its king and the city of Samaria as its capital; and the southern "Kingdom of Judah" with its capital Jerusalem, where Rehoboam ruled over the two tribes (Judah and Benjamin) that remained loyal to the royal house of David. The spiritual center of the land, however, remained Jerusalem, where the Holy Temple built by Solomon stood, and where every Jew was obligated to make a thrice-yearly pilgrimage for the festivals of Passover, Shavuot and Sukkot. Seeing this as a threat to his sovereignty, Jeroboam set up, on Sivan 23 of that year, roadblocks to prevent the people's pilgrimage to Jerusalem, introducing instead the worship of two idols, in the form of gold calves, which he enshrined on the northern and southern boundaries of his realm.
The barricades remained in place for 223 years, until Hoshea ben Elah, the last king of the Northern Kingdom, had them removed on the 15th of Av of 574 BCE. By then, the ten tribes residing there were already being expelled from the land in a series of invasions by various Assyrian and Babylonian kings. The last of these occurred in 556 BCE, when Shalmaneser of Assyria completely conquered the Kingdom of Israel, destroyed its capital, exiled the last of the Israelites residing there, and resettled the land with foreign peoples from Kutha and Babylon. These peoples -- later known as the "Samaritans" -- assumed a form of Judaism as their religion, but were never accepted as such by the Jewish people; they subsequently built their own temple on Mount Gerizim and became bitter enemies of the Jews. The "Ten Lost Tribes of Israel" were never heard from again, and await the coming of the Moshiach to be reunited with the Jewish people.
Even after Haman was hanged on the 17th of Nissan of 357 BCE, his evil decree "to destroy, kill and annihilate all the Jews, from young to old, infants and women, in one day, the 13th day of the 12th month (Adar)" remained in force. Queen Esther pleaded with King Achashverosh to annul the decree, but Achashverosh insisted that "a writ that has been written in the king's name, and sealed with the king's seal, cannot be returned." Instead, he suggested to Esther and Mordechai to "inscribe, regarding the Jews, as you please, and seal it with the king's seal." On the 23rd of Sivan, Mordechai drafted a royal decree giving the Jews the license to defend themselves and kill all who rise up against them to kill them, and dispatched it to all 127 provinces of Achashverosh's empire. (Book of Esther, chapter 8)

A Momentous Year
R. Yaakov Pollack served as rabbi first in Prague and then in Cracow. In Cracow he established a large yeshiva that attracted thousands of students. R. Yaakov devised a new method of Talmudic study known as pilpul, with the goal of stimulating the intellectual abilities of his students. Although many scholars of subsequent generations opposed this method, R. Yaakov succeeded in bringing about a renewal of Talmudic study in Poland, which became a major Torah center for the next four centuries.

There are two sorts of inner convictions of the soul, this thing we call faith.
Unbound by the confines of space and time, your soul sees a reality your mind cannot fathom. From that vision seeps down a conviction that G-d is with you, that He is good, and that there is really nothing else but Him.
Not because you understand. But because your soul sees that this is so. And she sees with a clarity and certainty the flesh eye could never attain.
Nevertheless, a higher vision means there are two and not one: There is you and there is the vision you perceive. And if there are two, two can be separated.
So that, when darkness and confusion swells and storms, threatening to rip you away from your G-d, a higher vision is not enough.
That is when you need to reach to the very core of your soul. Not to that place in the soul that sees G-d, but to the essence of the soul that is truly a part of G-d.
To say, "This is my G‑d. I am His, He is mine, and we are one."
"And so, nothing can stand between us."
